The client wanted to find color-changing technology for polymer applications across industries such as packaging, construction, and electronics. Most partner scouting studies follow a company-first approach. They identify 25–30 entities, score them using generic parameters, and recommend a top three. This can create false equivalence.
The market includes different types of color-changing solutions. Some respond to temperature, some to light, some to electricity, pressure, water, chemicals, or lasers. These solutions also differ by format, including masterbatches, inks, coatings, and films. Their polymer compatibility and commercial readiness also vary. A thermochromic masterbatch and an electrochromic film are not the same type of solution and should not be compared as if they are.
Therefore, GreyB identified the need for a different approach for its client. The goal was to compare partners within each stimulus category and answer two questions:
- For each type of color change, which partner is the best fit?
- How does the known partner compare in that specific category?
Building the Search around Stimulus Categories
GreyB first mapped the different ways a material can change color. These included temperature, light/UV/IR, electricity, pressure, water or moisture, chemical or gas exposure, and laser response. Each stimulus became a separate search track. This helped avoid blind spots from the start.
For each stimulus category, the team searched for real, commercially available solutions across company websites, industry databases, product catalogs, trade publications, and third-party sources. The focus was limited to polymer-compatible, ready-to-use formats such as masterbatches, inks, coatings, and films.
Patents were not used for broad landscape mapping. Once a solution was identified, the team reviewed its associated patents to understand the color-changing mechanism, validated substrates, and whether the technology was proprietary. This added more depth than website information alone.
Comparing Solutions within the Right Category
All identified solutions were evaluated using a structured framework. The framework covered technical feasibility, implementation viability, and partner feasibility. Scoring and ranking were done within each stimulus category. Thermochromic solutions were compared only with thermochromic solutions. Photochromic solutions were compared only with photochromic solutions. The known partner was used as the constant benchmark across every category.
GreyB also gathered details that were not publicly available through direct outreach to selected solution providers. These included performance data, indicative pricing, customization feasibility, processing compatibility, lead times, and production capacity. This ensured the final evaluation was based on validated information, not only website claims.
Moving Beyond a Single Ranked List
The final output was organized stimulus by stimulus. For each type of color-change technology, specific suppliers were identified as the best fit. Recommendations were separated into short-term and long-term partners. Short-term partners had commercialized, ready-to-use solutions.
Long-term partners had strong proprietary R&D and customization capability. Every shortlisted supplier was benchmarked directly against the known partner. This helped answer what each supplier offered that the known partner did not, where they fell short, and whether the client should stay, switch, or complement the known partner.
What the Study Made Clear
Cross-category rankings can create false equivalence. Ranking thermochromic, electrochromic, and piezochromic solutions together can produce a single list that is methodologically weak. A mediocre solution in a crowded category can outrank a strong solution in a niche category because of scoring weights. Within-category ranking avoids this issue.
The study also showed that the known partner was not equally strong across all stimulus types. Many providers are strong in one or two categories but average or absent in others. A single top-three ranking would hide this. Stimulus-wise benchmarking showed where the known partner led, where alternatives performed better, and where a multi-partner strategy was needed.
It was also found that short-term and long-term partnerships require different criteria. A partner with ready-to-use masterbatches may be useful for immediate needs. A partner with proprietary technology and R&D capability may be better for long-term differentiation. Treating all partners on one timeline can mislead decision-making.
Building a Clearer Partner Selection Framework
The study helped the client move beyond the limits of traditional partner scouting. Instead of presenting one ranked list as objective truth, GreyB delivered stimulus-wise rankings, a constant benchmark against the known partner, and clear short-term and long-term recommendations. This gave the client a transparent and actionable view of the color-intelligence technology landscape.
The client could decide whether to stay with the existing partner or switch, but also for which technology types, on what timeline, and with what trade-offs. The stimulus-first methodology was also adopted as a reusable framework for technology scouting projects where different solution types cannot be meaningfully compared in a single ranking.
