Food Dyes Banned in Europe but Allowed in the US: What's Actually True

Most US food dyes are not banned in Europe. Red 40, Yellow 5 and Yellow 6 are legal in the EU with a warning label about children’s activity and attention. The real differences are narrower: Green 3, Citrus Red 2 and Orange B are not authorized there, Red 3 is tightly restricted, and titanium dioxide has been banned since 2022.

The idea that Europe protects its citizens from additives Americans are fed every day spreads because it feels true. In some cases it is true. But the most-shared version, that Red 40 and Yellow 5 are “banned in Europe,” is not. You deserve the precise picture, because the real differences are interesting in their own right.

The short answer

• Allowed in both, but labeled in the EU: Red 40, Yellow 5, Yellow 6.
• Allowed in both, no special label: Blue 1, Blue 2.
• Not authorized in the EU: Green 3, Citrus Red 2, Orange B.
• Heavily restricted in the EU, revoked in the US: Red 3.
• Banned in the EU, still allowed in the US: titanium dioxide (a white color, not a dye in the usual sense).

US food dyes vs EU rules: the full table

Status as of October 7, 2026.

The warning label explained

EU law (Annex V of Regulation 1333/2008) requires foods containing any of six colors to state the color’s name or E number followed by: “may have an adverse effect on activity and attention in children.”

The six are E102 (tartrazine), E104 (quinoline yellow), E110 (sunset yellow), E122 (carmoisine), E124 (ponceau 4R) and E129 (Allura Red). Three of them are US dyes: Yellow 5, Yellow 6 and Red 40. The label followed a 2007 trial from the University of Southampton that found small increases in hyperactivity in children given dye mixtures. We cover that study in detail in Is Red 40 bad for you?

The label is not a ban, but it has an effect. Few brands want that sentence on a children’s snack, which is a big part of why European versions of some American products are colored with plant extracts instead.

The real differences, one by one

Red 3 (erythrosine). In the EU, erythrosine is permitted only in a few kinds of preserved cherries. In the US it was used much more widely, in candy, frostings and some drugs, until the FDA revoked its authorization in food on January 15, 2025. The legal reason was the Delaney Clause, which bans any color additive found to cause cancer in humans or animals. Studies showed cancer in male rats at high doses. The FDA noted that the mechanism behind those tumors does not occur in humans and that human exposure is typically much lower. Food makers have until January 15, 2027 to comply, and the FDA has urged them to move sooner.

Green 3 (Fast Green FCF). Approved in the US but not authorized as a food additive in the EU. It is one of the six dyes in the FDA’s voluntary phase-out.

Citrus Red 2 and Orange B. Both were narrow, little-used US approvals: Citrus Red 2 for coloring the skins of oranges, and Orange B for the casings or surfaces of frankfurters (hot dogs). Neither is authorized in the EU. In July 2026 the FDA finalized revoking Orange B, effective September 8, 2026, and proposed revoking Citrus Red 2, in both cases because industry had abandoned their use. The comment period on Citrus Red 2 closed on August 24, 2026. As of early October 2026 we could not find a final order.

Titanium dioxide (E171). This is the clearest case of the EU being stricter. After the European Food Safety Authority concluded in 2021 that a concern about genotoxicity (damage to DNA) could not be ruled out, the EU withdrew E171’s authorization, with a transition period that ended on August 7, 2022. In the US it remains allowed at up to 1% of a food’s weight. The FDA is reviewing a 2023 petition to repeal that approval, and has said it disagrees with parts of EFSA’s assessment, arguing that some of the materials tested did not represent the additive actually used in food.

The other direction: dyes Europe allows and the US does not

The comparison runs both ways. Several synthetic colors permitted in the EU are not on the FDA’s list of approved food colors. They include quinoline yellow (E104), carmoisine (E122), ponceau 4R (E124), patent blue V (E131), green S (E142) and brilliant black (E151). Three of them are on the EU’s own warning-label list. Neither system is simply “stricter.” Each has approved and rejected different substances.

What is changing in the US

• Red 3 is out of food from January 15, 2027.
• Orange B is revoked and Citrus Red 2 is proposed for revocation.
• The other six certified dyes, Red 40, Yellow 5, Yellow 6, Blue 1, Blue 2 and Green 3, are the target of a voluntary phase-out the FDA now aims to complete by the end of 2027. The original April 2025 announcement said the end of 2026. Many large food companies have published pledges, which the FDA tracks.
• New natural colors have been approved as replacements, including Galdieria extract blue, butterfly pea flower extract, calcium phosphate, gardenia blue and beetroot red.

The bottom line

The US–EU dye gap is real but narrower than the internet suggests. Europe mostly regulates the common US dyes by labeling them, not banning them. The sharpest real differences are titanium dioxide and a few little-used dyes. The US is now closing several of those gaps. If you want to avoid synthetic dyes, you do not need to buy imported food. You need to read the label, and cooking more of your own food makes that easy.
