1. Recycled Materials
Color management in recycled plastics, fibers, paper, and other recovered substrates.

What is the biggest misconception companies have about recycled materials?

The most common misconception is that recycled materials should behave exactly like virgin materials in every situation. Recycled content can absolutely perform extremely well — but it requires different expectations, tighter process controls, and a more collaborative approach across the supply chain. Companies that go in expecting a direct drop-in replacement tend to be caught off guard by the level of adjustment required in sourcing, processing, testing, and quality management. This applies whether you are working with post-consumer recycled plastics, recycled paper and board, or recovered textile fibers.

What are the most common process mistakes that create color inconsistency with recycled content?

The biggest mistake is not having a structured way to handle the variation that exists in incoming feedstock. Some manufacturers invest in melt filtration systems (for plastics) or other homogenization steps to manage what they receive, but these are expensive and time-consuming to maintain. The more sustainable answer is upstream: gaining control of the feedstock itself, through better supplier specifications, more rigorous incoming material testing, and stronger supplier accountability. Trying to correct for variability inside the production process is always going to be more costly and less effective than preventing it at the source.

Where do companies most commonly underestimate the challenge of using recycled content?

Most companies underestimate how much feedstock variability impacts everything downstream. The assumption that recycled resin, fiber, or board is a simple substitution for virgin material is where things tend to go wrong. Successful implementation of recycled content requires adjustments across the entire operation — not just in the lab, but in sourcing strategy, processing parameters, testing protocols, and quality management systems. Companies that recognize this early and build their processes accordingly tend to have a much smoother experience.

We work with light colors like yellows, oranges, and reds. Is it possible to achieve these consistently with recycled content?

This is one of the most challenging areas in recycled materials color management. Light colors have very little room to hide base material variation. With darker or high-chroma colors, the pigment load can effectively mask what is underneath — but with yellows, oranges, whites, and light neutrals, the base material color has a direct influence on the final result. Depending on how much the LAB values of the incoming feedstock shift from lot to lot, achieving consistent light shades can require significantly higher pigment loads, which increases raw material cost, or may simply not be consistently achievable beyond a certain recycled content percentage. The key is to measure and understand your base material color before formulating, and to build that variability into your specifications and customer expectations from the start.

Does this challenge differ between recycled plastics, recycled fibers, and recycled paper?

Yes, each substrate presents different challenges. Recycled plastics are sensitive to polymer type mixing and thermal history, which can affect both color and mechanical performance. Recycled paper and board carry inherent color variability from the mix of recovered grades, and optical brightening agents from the original fiber can behave unpredictably. Recycled textile fibers face dye stripping variability and residual color that makes achieving pale or bright shades particularly difficult. The measurement and specification principles are similar across all three, but the specific parameters to control — and the tolerances that are realistically achievable — differ by substrate.

What is the best way to set color tolerances and specifications with recycled material suppliers?

Formally, in writing, and with verification built in. Many companies accept recycled feedstock based on volume and delivery agreements alone, without any color specification — and then spend significant time and money trying to manage the consequences on the production floor. The more effective approach is to develop your own internal criteria based on what you know works for your operation: LAB values, physical testing characteristics, and processing requirements. These specifications should be formalized in supplier contracts, with a requirement for certificates of analysis on every incoming lot. And you can take this even further by engaging directly with your suppliers’ upstream processes — understanding where their feedstock comes from and how it is sorted — so that you are not just reacting to what arrives but actively influencing the quality of what is produced.

We sometimes see color differences batch to batch, but not within a single batch. Is that normal?

Yes, and it is actually a sign that your within-production process is reasonably well controlled. Batch-to-batch variation driven by lot-to-lot differences in incoming feedstock is the most common and persistent challenge in recycled material color management. Within-batch consistency is generally more controllable, and companies with strong supplier relationships and rigorous incoming material verification tend not to see significant within-batch issues. If you are experiencing within-batch variation, that is worth investigating separately, as it usually points to a process or equipment issue rather than a feedstock issue. For the batch-to-batch challenge, the most effective approach is spectrophotometric measurement of incoming lots before they enter production. The key mindset shift is treating your supplier relationship as a quality partnership, not just a procurement transaction. On the measurement side, spectrophotometric verification of incoming lots against your defined LAB standards gives you an objective, repeatable basis for acceptance decisions — removing subjectivity and creating a clear record of compliance over time.

Is AI and machine learning being used to solve color problems in recycled materials?

Yes, and it is an area that is developing quickly. The most mature application today is in the sorting stage, where AI-assisted optical systems are helping to identify and separate polymer types and colors more accurately at material recovery facilities. This is directly improving feedstock consistency for manufacturers who source from operations using this technology. At the formulation stage, there is growing interest in using AI to better predict how a given base material will behave and to accelerate formula development. Smarter softwares are making this process faster and more accurate, and this is an area where the technology will continue to advance significantly.
Minimizing material, chemical, and energy waste in color development, production, and quality control.

Where does the most avoidable waste occur in color production?

The two largest sources of avoidable waste in color production are off-spec production runs and excessive color trials during development. Off-spec runs happen when incoming material variability is not caught before it reaches the line, or when process parameters drift outside the window that was established during color approval. Excessive development trials happen when formulation is done by eye or by iterative guesswork rather than with predictive spectrophotometric tools. In both cases, the result is material that must be downgraded,

How does better color measurement reduce material waste?

Spectrophotometric measurement gives you objective, quantified data at every step — incoming material, in-process, and finished product. When that data is used proactively, rather than just for pass/fail inspection at the end, it allows you to intervene earlier and with more precision. You catch incoming lots that are outside tolerance before they reach the line. You detect process drift before it produces off-spec product. You approve color formulations with fewer physical trials. Each of these interventions reduces the amount of material that ends up as waste or rework.

Can digital color formulation reduce the number of physical trials needed?

Significantly. Digital formulation tools that combine accurate spectrophotometric measurement of substrates and colorants with predictive algorithms can get a formulator much closer to the target before any physical sample is produced. In operations that have historically relied on manual adjustment and iterative physical trials, moving to digital formulation typically reduces formulation time by up to 50%, what can mean a huge reduction in the amount of trials. That reduction translates directly into less colorant used, less substrate consumed, less processing energy, and less waste.

What role does tolerance setting play in waste reduction?

Tolerances that are tighter than necessary generate waste by rejecting acceptable product. Tolerances that are too loose generate customer complaints and downstream rework. Getting tolerances right — based on what is actually perceptible to the end observer under the intended viewing conditions, and what is practically achievable with your specific substrate and process — is one of the highest-leverage decisions in color quality management. Many operations are running tighter tolerances than their customers actually require, and the waste consequence of that misalignment is significant.

How can we reduce waste from color changeovers in production?

Color changeovers are a major source of waste in continuous production environments. The keys to minimizing changeover waste are sequencing (moving from lighter to darker colors where possible), purge optimization (using the right purge compound in the right quantity rather than defaulting to maximum purge cycles), and precise in-process measurement to confirm when the previous color is fully cleared before beginning the new run. Digital tools that model the changeover process and predict the point of color stability can further reduce purge material and startup waste.
Evaluating the environmental and performance profile of pigments, dyes, and effect materials.

What makes a pigment or colorant more or less sustainable?

Sustainability in colorants involves multiple dimensions: the environmental impact of raw material extraction and synthesis, the presence of hazardous substances (heavy metals, restricted amines, persistent organic compounds), the energy intensity of production, end-of-life behavior in recycling and composting streams, and durability in use (since a colorant that fades quickly forces earlier replacement of the product). No single metric captures all of these dimensions, which is why life-cycle thinking is important when evaluating colorant options.

Are there colorants that interfere with recycling, and how do we identify them?

Yes, this is an increasingly important area of focus. Certain pigments and dyes — particularly some carbon blacks, fluorescent colorants, and specific organic pigments — can interfere with near-infrared sorting systems used at material recovery facilities, causing misidentification of polymer type and contamination of recycling streams. The RecyClass and CIEL protocols, among others, provide guidance on which colorants are problematic for specific packaging types. As design-for-recyclability regulations tighten in many markets, colorant selection is

What are bio-based pigments and are they ready for commercial use?

Bio-based pigments — derived from plant, algae, fungal, or microbial sources — are an active area of development. Some are already in commercial use for textile dyeing. Others remain in earlier development stages and face challenges around color consistency, lightfastness, processing compatibility, and cost at scale. For most industrial color applications, bio-based pigments are not yet a direct drop-in replacement for conventional synthetic pigments, but the technology is advancing and the regulatory and brand pressure to develop alternatives to petrochemical-derived colorants is significant.

How do heavy metal regulations affect colorant selection?

Regulations restricting cadmium, lead, chromium VI, and other heavy metals in colorants have progressively tightened across major markets over the past two decades, and this trend continues. For most applications, compliant alternatives exist and have been adopted by responsible formulators. However, some high-performance colorant applications — particularly for certain engineering plastics requiring extreme heat stability — have fewer alternatives, and the transition has been more difficult. Staying ahead of regulatory change requires active engagement with your colorant suppliers and awareness of evolving requirements in your target markets.

How can digital Color Management help us use more eco-friendly substances?

Using modern formulation tools is one of the more practical and immediate sustainability applications of digital color management workflows. When a pigment is restricted by regulation — such as certain heavy metal-based colorants under REACH or RoHS — or when a brand decides to phase out a substance for environmental or reputational reasons, the challenge is finding an alternative that matches the original color as closely as possible without disrupting the rest of the formula or the production process. Doing this manually, by iterative physical trials, is time-consuming and expensive. Formulation software addresses this by allowing you to define the colorants that are available or preferred — and exclude those that are restricted or undesirable —, and then calculating substitute recipes that hit the same spectrophotometric target using the approved palette. The software can also flag when a currently used pigment appears on a watch list or conflicts with a regulatory profile you have defined, effectively building compliance awareness into the formulation workflow rather than treating it as a separate step.

What is the relationship between color intensity and sustainability?

Higher color intensity (chroma or saturation) generally requires higher pigment loads or more complex colorant combinations, both of which increase material consumption and cost. There is also a recyclability dimension: highly saturated colors are more likely to affect the perceived quality of recyclate, which can reduce the value and application range of the recovered material. This does not mean that saturated colors are inherently unsustainable, but it does mean that the sustainability profile of a highly saturated colored product requires more attention to colorant selection, recyclate impact, and end-of-life pathway than a more neutral palette.
How digital color communication and shared data reduce waste, misalignment, and inefficiency across the supply chain.

What is the core problem that digital color communication solves?

Color is traditionally communicated through physical samples, verbal descriptions, and visual judgment — all of which are imprecise and interpreted differently by different people under different conditions. A sample that looks approved in one lighting environment can look wrong in another. A color described as “warmer” means something different to a brand manager than to a lab technician. Digital color communication replaces these ambiguous exchanges with spectrophotometric data: objective, repeatable numbers that mean the same thing regardless of who is reading them or where. That shift alone eliminates a significant share of the misalignments that generate rework, rejections, and wasted material across the supply chain.

How does poor color communication generate waste?

In global supply chains, a single color development cycle can involve a sample traveling intercontinental distances multiple times — between brand, supplier, and manufacturer — before an approval is reached. Each round of shipping takes time, consumes resources, and introduces new opportunities for the physical sample to be viewed under different conditions and interpreted differently than it was at origin. When both parties work from shared spectrophotometric data and standardized virtual viewing conditions instead, many of those rounds become unnecessary. The carbon and resource cost of sample logistics is easy to overlook, but in operations with high development volumes it is far from negligible.

How does shared color data reduce rejections?

Many rejections at goods receipt happen not because the product is genuinely out of tolerance, but because the client and vendor were never working from the same numerical standard in the first place. Maybe one side was matching to a physical standard and the other was working from a different measurement geometry or illuminant. When both parties share a single digital color standard with agreed measurement conditions, illuminant, observer, and tolerance parameters, the basis for acceptance is unambiguous from the start. Rejections driven by miscommunication rather than genuine quality failures largely disappear.

What’s the relevance of a digital color library for sustainability?

A structured digital library of approved colors, substrates, and formulations is a sustainability asset that is easy to underestimate. It prevents the same color from being developed from scratch multiple times across different projects or product lines. It makes it straightforward to identify which existing approved formulation is closest to a new target, reducing unnecessary development work. It also provides the historical data needed to track consistency over time and to identify suppliers or material lots that are drifting — before that drift causes a production problem. Finally, it helps avoid stress with clients that expect you to always be able to go back to a color that was developed before.

How sound color management practices contribute to the long-term financial health, competitiveness, and reputation of a business.

How does color management quality affect the long-term financial health of a business?

Color errors are expensive in ways that go beyond the immediate cost of a rejected batch. Off-spec production consumes raw materials, energy, and labor that cannot be recovered. Rework disrupts scheduling and reduces effective capacity. Customer complaints erode relationships that took years to build. When color management is treated as a peripheral quality function rather than a core operational discipline, these costs accumulate quietly and persistently. Companies that invest in rigorous color management tend to find that the financial return, through waste reduction, fewer rejections, shorter development cycles, and stronger customer retention, significantly outweighs the investment.

What is the relationship between color consistency and brand equity?

For brand owners, color is one of the most immediate and recognizable expressions of brand identity. Inconsistency across products, markets, or production runs erodes the perception of quality and reliability that brand equity depends on. This is particularly acute in categories that heavily rely on brand advocacy or where color is a primary purchase driver, such as cosmetics, fashion, consumer electronics, automotive, etc. A color management infrastructure that delivers consistency across suppliers, geographies, and substrate variations protects that equity in a way that is difficult to quantify but very easy for consumers to notice when it fails.

How does regulatory exposure relate to color practices specifically?

Regulations restricting certain colorants, mandating recycled content, and requiring recyclable packaging design are tightening across major markets and the pace of change is accelerating. Companies that have not modernized their color practices face growing compliance risk, not just in their own operations but across their supply chains, where restricted substances or non-recyclable colorant choices can create liability. Proactive color management, with supplier qualification, incoming material verification, and colorant compliance tracking built into standard workflows, converts that regulatory risk into a manageable process rather than a recurring crisis.

What role does color management play in supply chain resilience?

Supply chain disruptions, whether from raw material shortages, geopolitical instability, or regulatory changes, hit the hardest on companies that have the least flexibility. A well-managed color operation, with digital recipe libraries, qualified alternative suppliers, and the formulation capability to substitute materials quickly, can adapt to disruption far faster than one that relies on a handful of unqualified sources and undocumented processes. Resilience, in this sense, is a direct function of how well color knowledge is captured, organized, and made actionable across the organization.

How does a strong color management culture affect a company's reputation with partners and clients?

Clients and partners notice operational maturity. A supplier that communicates in spectrophotometric data, responds to quality questions with trend analysis rather than anecdote, and proactively flags potential issues before they become problems signals a level of professionalism that builds confidence and deepens relationships. In an industry where personal relationships have historically driven much of the business, this kind of operational credibility is becoming an equally important differentiator, particularly as sustainability disclosures require companies to demonstrate, not just claim, that their practices meet the standards they are committing to publicly.
How color management practices reflect and shape a company’s relationships with its people, its partners, and the broader community.

What are the main worker safety concerns related to colorants and pigments?

Colorant manufacturing and handling involve several categories of occupational hazard. Dust exposure during dry pigment handling is a respiratory risk, particularly for inorganic pigments and carbon blacks. Solvent exposure to certain ink and coating applications carries both acute and chronic health risks. Some specialty pigments and dyes involve synthesis intermediates with carcinogenic or sensitizing properties. Responsible operations address these risks through engineering controls, appropriate PPE, industrial hygiene monitoring, and worker training. When evaluating colorant suppliers, their safety management practices — not just their product compliance — are part of the due diligence picture.

How does color management quality affect the day-to-day experience of the people working with it?

Poor color management creates frustration at every level of an organization. Production teams deal with last-minute corrections, unexplained rejections, and pressure to make judgment calls they are not equipped to make consistently. Lab technicians spend time on rework and firefighting rather than development. Sales and account teams manage difficult conversations with clients about delays and inconsistencies that feel avoidable. When color processes are well defined, well measured, and well communicated, that pressure is reduced and the people doing the work can focus on doing it well rather than compensating for systemic gaps.

What color training has to do with sustainability?

Color knowledge within production and quality teams is often informal, passed down through observation rather than structured learning, and inconsistent as a result. When a company invests in proper color training, giving its people a real foundation in color science, measurement, and communication, it signals that it takes their professional development seriously. It also produces practical results: better decisions, fewer errors, and a team that can articulate and defend color quality standards rather than relying on intuition. The two are not separate; treating people as professionals worth investing in and getting better operational outcomes are the same thing.

How does the quality of supplier relationships affect the people on both sides of them?

Transactional supplier relationships, defined purely by price, volume, and delivery, place all the risk and pressure on the supplier and create an adversarial dynamic that is felt by the people managing those relationships on both sides. When a client and supplier work collaboratively on color quality, sharing data, aligning standards and troubleshooting problems together, the relationship becomes genuinely productive for both. The people involved spend less time in conflict and more time solving real problems. In the context of recycled materials especially, where variability is real and shared, a collaborative relationship is not just more pleasant, it is the only model that is actually sustainable.

What does fair and transparent communication with clients look like in the context of color?

Overpromising on color creates problems that are ultimately paid for by people: production teams under pressure to hit an impossible target, account managers managing a dissatisfied client, and a supplier relationship that starts in mistrust. Honest communication about what is achievable, what the constraints are, and what the tolerance framework will look like is not just ethically better, it is the foundation of a client relationship that can last. Clients who understand the real parameters make better decisions and are more resilient partners when things do not go perfectly.

How can color teams contribute to a culture of sustainability within their organization?

Color teams sit at an intersection that is unusually visible: they touch materials, suppliers, production, and clients all at once. That position gives them a natural role in carrying sustainability values across the organization, surfacing colorant compliance issues, flagging supplier practices that do not meet the company’s stated standards, advocating for investment in tools and processes that reduce waste, and modeling the kind of careful, data-driven decision-making that good sustainability practice requires. A color team that understands its work as part of a broader organizational commitment, rather than a purely technical function, can have an outsized influence on the culture around it.

Can digital transformation in color management become a social sustainability risk?

Digital transformation in color management is often framed as a question of technology, but the harder challenge is human. Color knowledge in most organizations lives in people: the experienced technician who can read a batch by eye, the lab manager who has built supplier relationships over decades, etc. When new tools arrive without care, those people can feel that what they know, or even themselves, is being replaced rather than extended. The result is disengagement, fear, and the quiet loss of knowledge that no software can recover. The organizations that navigate this well involve their experienced people as contributors to the transition, not recipients of it. A technician who learns to work with digital tools does not become less valuable, they become more so. Transformation that people feel safe in moves faster and produces better outcomes, and in a field where tacit human knowledge is still irreplaceable, that is not a soft consideration.
