Why Process Matters
Mixing gets you the color. Not the shelf life.
Spirulina + turmeric = green.
Green + heat = yellow.
Same pigments, different process. That is why DyeConverter matches to your pH, heat, light and shelf life, not just to a shade card.

Frequently Asked Questions
Frequently asked questions.
DyeConverter™ (also written Dye Converter) is an AI-powered platform that helps food and beverage companies transition from artificial dyes to natural, plant-based color alternatives. It provides instant recommendations with precise ppm ranges, regulatory compliance data, and supplier information--cutting reformulation time by up to 80%.
On April 22, 2025, the FDA and HHS announced a complete phase-out of petroleum-based artificial food dyes (Red 40, Yellow 5/6, Blue 1/2, Green 3) by December 2027. Approximately 19% of all packaged foods in the U.S. contain artificial dyes and must be reformulated. This represents roughly $57 billion in annual retail sales across thousands of SKUs.
We offer several ways to work together, sized to your team and your goals. Pro is seat-based licensing (one or two seats, billed quarterly or yearly) with full access to the platform, database, and regulatory data. Enterprise is built around custom packages--API access, exclusive tenancy, white-label deployment, and SSO for large-scale CPGs. We also offer white-glove search, where our team runs the reformulation for you. And each quarter we grant access to qualifying startups and companies under $5M in revenue. Reach out through our pricing page to start a conversation.
Traditional reformulation with consultants costs $20,000–$100,000 per SKU and takes 12–18 months. DyeConverter™ reduces this to days or weeks at a fraction of the cost. With unlimited SKUs included in Pro and Enterprise plans, your first successful reformulation typically pays for the entire annual subscription--delivering 2-10× ROI.
Our recommendations are grounded in regulatory frameworks like FDA 21 CFR, EFSA, and Codex Alimentarius, layered with global ingredient resources and datasets, supplier archives, and spec sheets from our network of verified natural-color suppliers. New suppliers enter this market constantly, and those direct relationships are often where the most specific, sometimes gated, information actually lives, well before it shows up in any public database. We back all of it with food science and technology research: peer-reviewed literature on botanicals, plant-based colorants, and stability science, so every match is grounded in both regulatory reality and the science behind it.
Yes. Every natural colorant alternative includes built-in regulatory guardrails for FDA, EFSA, and Codex GSFA compliance. We provide complete regulatory status by region, approved usage levels (ppm), and documentation to support your compliance teams through the reformulation process.
DyeConverter™ supports reformulation across 50+ food categories including beverages (38.8% of natural colorant market), bakery, confectionery, dairy, frozen products, savory snacks, sauces, and more. Our AI adjusts recommendations based on pH, heat stability, light exposure, and shelf life requirements specific to your application.
Our platform delivers 98% conversion accuracy with FDA-approved alternatives. Each recommendation includes precise ppm usage ranges, stability data, cost per kilogram, provenance information, and confidence scoring. We provide side-by-side comparisons to help you make informed decisions quickly.
Yes. We offer a guided demo that walks you through a real reformulation scenario so you can see exactly how the platform works with your use case. Contact us through our contact page and we'll set up a personalized walkthrough with our team.
