Synthetic food colors are under active regulatory review across major markets, and brands are being asked a question that did not exist a decade ago: what does it take to switch to plant-based colors without disrupting production, labels, or shelf life? The answer is not a single ingredient swap - it is a sequence of regulatory, formulation, and documentation steps. This roadmap walks through the five stages of a color transition, in the order they should happen, and the distinctions that most often trip up product teams and their suppliers.
This article provides general information, not legal advice. Confirm requirements for your products and markets with your own regulatory specialists.
Why the Regulatory Ground Is Moving
- United States - federal level. In January 2025, the FDA announced the revocation of the authorization for FD&C Red No. 3 in food and ingested drugs, with transition timelines for manufacturers (food products and ingested drugs have separate compliance dates) [3]. At the same time, the agency has been expanding the list of plant-derived colors that are exempt from batch certification: in February 2026, the Federal Register carried listings for Beetroot Red [1] and Spirulina Extract [2] as color additives exempt from certification - a signal that the pathway for naturally derived colors is being actively developed.
- United States - state level. California's AB 2316 (the California School Food Safety Act, signed in 2024) prohibits six synthetic dyes - Red 40, Yellow 5, Yellow 6, Blue 1, Blue 2, and Green 3 - in food sold at K–12 public schools, starting in 2028 [6]. For brands with education-channel products, this is a fixed reformulation deadline.
- European Union. Food colors are regulated under a positive-list system: Regulation (EC) No 1333/2008 sets out the authorized food additives, their conditions of use, and labeling requirements [4]. EFSA carries out scientific assessments of colors before authorization and during re-evaluation programs [5]. In practice this means an EU-listed color is safe to use only within its listed conditions - and that a plant-based alternative must be either an authorized additive or correctly classified as a food ingredient.
The combined effect is a market where legacy synthetic colors face narrowing windows, while plant-derived options are gaining regulatory clarity. That is a manageable transition - if it is planned as a project rather than treated as a last-minute substitution.
Step 1 - Audit Every Color in Your Portfolio
Start with a complete inventory, because transitions fail when one product is forgotten:
- Every colorant in every SKU, with its name, E number or CI designation, and current use level.
- Every market where the product is sold, including sub-national markets with their own rules.
- Every channel: retail, foodservice, and school or institutional channels often have different exposure.
- Every declaration already on pack, since labeling follows the ingredient.
Rank products by urgency - regulatory deadline, channel exposure, and share of revenue - and tackle the top tier first.
Step 2 - Map Your Regulatory Jurisdictions
| Market | Framework | What it means for a color switch |
|---|---|---|
| United States | FD&C Act color additive framework | Colors are either subject to FDA batch certification or listed as exempt from certification [1, 2] - the two paths carry different evidence and labeling implications |
| European Union | Regulation (EC) No 1333/2008 [4]; EFSA assessments [5] | Colors must be on the authorized list and used within listed conditions |
| US states | State-level statutes (e.g., California AB 2316 [6]) | State rules can be stricter than federal rules and set their own deadlines |
A single reformulation rarely satisfies every market. Decide early whether to harmonize on one color system globally or to maintain market-specific formulas - this decision drives cost, SKU count, and supply chain complexity.
Step 3 - Colour Additive or Colouring Food? Know Which Path You Are On
This is the distinction that most often causes late-stage surprises.
In the United States, a plant-derived color is typically used either as a color additive listed in the relevant FDA regulations (which may be exempt from certification, as with the recent beetroot red and spirulina extract listings [1, 2]) or as a food ingredient in its own right, depending on how it is produced, standardized, and declared.
In the EU, concentrates derived from foods and used to color foods may be classified as "colouring foods" rather than as additives, which affects whether an E number appears on the label. The classification depends on the production process and the resulting product, and it should be confirmed against current official guidance for your specific material [4].
The practical takeaway: before you brief your supplier on a color, decide which regulatory identity the ingredient will have in each market - because that identity determines the documentation you need, the labeling you will print, and sometimes the ingredient format itself.
Step 4 - Select and Validate Replacements
Color matching is where plant-based transition projects succeed or stall. Three dimensions matter at once:
Hue and intensity. Synthetic dyes deliver narrow, intense, highly stable hues. Plant colors cover the same broad palette - reds from anthocyanin-rich sources and beetroot, yellows and oranges from carotenoid sources such as marigold, beta-carotene, and turmeric, blues from spirulina-based options - but each arrives with its own color character, and often needs a blend to match a target shade.
Process and stability. Stability in your matrix is not optional: pH, heat, light, and shelf life all shape how a plant color performs, and different pigment families behave differently in bakery versus beverage systems [7]. Validate candidates against your real process before committing.
Labeling and claims. The replacement changes your ingredient declaration. Check how each candidate must be declared in each market, and avoid claims your evidence cannot support.
Step 5 - Update Labels, Documents, and Supplier Agreements
A color change touches more documents than most teams expect:
Labels and artwork for every affected SKU and market, including any required warnings or declarations.
Specifications for the new ingredient: identity, assay or color value with method, microbiology, heavy metals, and allergen statement.
Batch documentation: certificates of analysis that state actual values rather than only "conforms," so incoming quality control has something to verify against.
Supplier agreements: change-notification clauses, since a silent raw-material change can invalidate your labeling work.
A Practical Transition Timeline
| Phase | Typical activity | Duration |
|---|---|---|
| 1 | Portfolio audit and jurisdiction mapping | 2–4 weeks |
| 2 | Candidate screening and bench trials | 3–6 weeks |
| 3 | Stability and shelf-life validation in final packaging | 4–8 weeks |
| 4 | Label updates, documentation, and supplier agreements | 4–6 weeks |
| 5 | Pilot production and phased switchover | 4–8 weeks |
Durations vary with product complexity, retail customer approval cycles, and inventory run-down. The critical path is usually stability validation and label change control - not ingredient sourcing.

FAQ
Do plant-based colors require FDA certification? Not necessarily. US colors fall into two groups: those requiring FDA batch certification, and those listed as exempt from certification - a category that includes many plant-derived colors, with recent additions such as beetroot red and spirulina extract [1, 2]. Which path applies depends on the specific listed use.
What are the compliance deadlines for FD&C Red No. 3? The FDA revoked its authorization for use in food and ingested drugs, with separate transition timelines for each category [3]. If Red 3 appears in your portfolio, treat the earlier food deadline as your planning date.
Does California's school food law affect my products? If you sell to K–12 public schools in California, AB 2316 prohibits six synthetic dyes in that channel starting in 2028 [6]. The practical response is to reformulate school-channel SKUs early and keep the formulas separate where needed.
What is the difference between a "colouring food" and a color additive in the EU? Food-derived concentrates used for coloring may be classified as colouring foods rather than additives, which changes labeling (for example, whether an E number appears). Classification depends on how the material is produced and declared - confirm it against official EU guidance for your specific ingredient [4].
How long does a full transition take? Most mid-complexity products take four to six months from audit to switchover, with stability validation and label change control on the critical path. Starting the regulatory mapping before formulation saves weeks.
