What is Blue 40 dye? It is Blue 1 (Brilliant Blue FCF), the blue version of Red 40.

Updated October 28, 2026

Blue 40 is not a real food dye. It is Blue 1 (FD&C Blue No. 1, Brilliant Blue FCF, E133): what it is made of, the blue version of Red 40, its FDA status, and real products whose labels list it.

Quick answer

Blue 40 is not a real food dye: the FDA has never listed a color called Blue No. 40, and the EU has none either. People who say “Blue 40” almost always mean FD&C Blue No. 1 (Brilliant Blue FCF, E133), the bright blue synthetic dye that sits next to Red 40 on candy and sports-drink labels. The only other certified blue is Blue 2 (Indigo Carmine, E132). Both are among the six petroleum-based dyes the FDA wants out of US food by the end of 2027.

01 · A closer look

Is Blue 40 a thing?

No. The federal list of certified (synthetic) colors for food, 21 CFR Part 74 Subpart A, has eight entries: FD&C Blue No. 1, Blue No. 2, Green No. 3, Red No. 3, Red No. 40, Yellow No. 5, Yellow No. 6 and Citrus Red No. 2. There is no Blue No. 40. (A ninth, Orange B, was revoked in July 2026, and Red 3 must be out of food by January 15, 2027.) The number is a listing number, not a shade or strength, so Red 40 does not imply a matching Blue 40. A package, menu, recipe or video that says “Blue 40” is almost always describing Blue 1.

02 · A closer look

Is there a blue version of Red 40?

The closest match is Blue 1. Both are FD&C certified colors that the FDA calls petroleum-based, both are on its list of six dyes it wants removed from food by the end of 2027, and they usually share an ingredient list (purple and green candy are blends). They are different chemicals, though: Red 40 is an azo dye, Blue 1 a triarylmethane dye, and only Red 40 needs the EU’s children’s activity warning.

03 · A closer look

What is Blue 40 made of?

Blue 40 does not exist, so the real question is what Blue 1 is made of. Federal rules define FD&C Blue No. 1 as principally the disodium salt of a synthetic sulfonated dye (chemically, a triarylmethane), with limits on lead, arsenic, chromium and manganese, and every batch must be certified by the FDA before it can be sold. It contains no plant or animal ingredients. Blue 2 is made differently: synthetic indigo, produced from aniline and formaldehyde, is heated with sulfuric acid, then purified. “Lake” forms such as Blue 1 Lake are the same dyes bound to aluminum so they do not bleed in candy shells, coatings and seasoning dust. Blue 1 is often blended with Yellow 5 to make green.

04 · A closer look

Blue dye names on an ingredient list.

Under FDA labeling rules a certified color must be named, usually in short form such as “Blue 1” or “Blue 1 Lake”, so a blue dye cannot hide behind “artificial color” on a US label. The exception is butter, cheese and ice cream, where added colors (other than Yellow 5) do not have to be declared at all. This checker matches every one of these names on every label it reads.

How blue dyes appear on labels
Label wording	What it means
Blue 1, Blue 1 Lake	Brilliant Blue FCF; the Lake form is bound to aluminum for coatings and candy shells
FD&C Blue No. 1	The full US name of Blue 1
Brilliant Blue FCF, E133	The common name and EU/UK code for Blue 1, seen on imported foods
Blue 2, FD&C Blue No. 2	Indigo Carmine, a darker, purplish blue
Indigotine, E132	Other names for Blue 2
Artificial color, color added (no name)	On a US label this should be a color exempt from certification, not Blue 1 or Blue 2; ice cream may list no colors at all

21 CFR 101.22(k): how colorings must be declared on food labels (eCFR)

05 · A closer look

Foods that commonly contain Blue 1.

The FDA lists confections, beverages, cereals, frozen dairy desserts, popsicles, frostings and icings as typical uses of Blue 1, and baked goods, cereals, snack foods, ice cream, confections and yogurt for Blue 2. In our catalog candy is the most common shelf for both (counts below). The products below are not a guess: their current label names a blue dye.

06 · A closer look

Is Blue 1 safe, banned or being phased out?

Blue 1 is approved by the FDA and in the EU. EFSA’s 2010 re-evaluation lowered its acceptable daily intake to 6 mg per kg of body weight. Its refined intake estimates at the maximum reported use levels were below that limit, though a less refined estimate put high-consuming children (the 95th percentile) above it. There is no federal ban: in April 2025 HHS and the FDA asked industry to stop using Blue 1 and five other petroleum-based dyes, and the FDA’s pledge tracker now targets the end of 2027. States go further: West Virginia barred Blue 1 from school meals from August 1, 2025 and treats food containing it as adulterated from January 1, 2028, and California’s School Food Safety Act (AB 2316) bars it from public school food from December 31, 2027. This is a label guide, not medical advice.

How to avoid blue dye.

Read the ingredient list for the names above, choose USDA Organic (synthetic dyes are not allowed), or pick foods colored with spirulina extract or butterfly pea flower extract, color additives that are exempt from certification and are not flagged as artificial dyes. The FDA has also approved gardenia blue and Galdieria extract blue as plant- and algae-based replacements. The table at the end lists products whose current label names no artificial dye.

Useful answers

What is Blue 40?

There is no Blue 40 food dye. People who say it almost always mean Blue 1 (FD&C Blue No. 1, Brilliant Blue FCF, E133). The other approved synthetic blue is Blue 2 (Indigo Carmine, E132).

Is Blue 40 a thing?

No. The federal list of certified food colors has Blue 1 and Blue 2 but no Blue 40. It is a mix-up with Red 40, the most common US dye, which usually appears on the same labels as Blue 1.

What is Blue 40 dye?

It is almost always Blue 1 dye, also called FD&C Blue No. 1 or Brilliant Blue FCF: the bright blue in sports drinks, candy, frosting and ice cream.

Is Blue dye 40 the same as Blue 1?

In practice, yes: “Blue dye 40” and “Blue 40” are mistaken names, and the dye people mean is Blue 1. Check the ingredient list, which must name the real dye.

What is Blue 40 made of?

Blue 40 does not exist. Blue 1, the dye people mean, is a synthetic dye sold as a disodium salt, batch-certified by the FDA, which groups it with the petroleum-based colors. It contains no plant or animal ingredients.

What is the blue version of Red 40?

Blue 1 is the closest: another FD&C certified synthetic dye on the same FDA removal list. It is a different chemical with a different EU intake limit and no EU warning label.

What is Blue 1 dye?

FD&C Blue No. 1, or Brilliant Blue FCF (E133), is a synthetic blue food dye approved in the US and EU. It appears on labels as Blue 1, Blue 1 Lake or FD&C Blue No. 1.

Is Blue 1 banned?

Not federally or in the EU. The FDA asked food makers to stop using it by the end of 2027, West Virginia treats food with it as adulterated from 2028, and California bars it from public school food from December 31, 2027.

Is Blue 1 the same as Blue 2?

No. Blue 1 is a bright turquoise; Blue 2 (Indigo Carmine) is a darker, purplish blue made from synthetic indigo. They are different chemicals with separate listings.

What gives food a natural blue color?

Spirulina extract and butterfly pea flower extract are the common ones; the FDA has also approved gardenia blue and Galdieria extract blue. They are not flagged as artificial dyes.

How the clean score works

No setup needed, and strict: a full 100 needs every additive group clear and a verified organic claim (animal foods also need a verified grass-fed or pasture-raised claim; wild seafood and salt, which have no USDA organic standard, are scored without the organic points, and plant-based milks, cheeses and proteins without the feeding claim). Points: the nine additive groups (seed oils, artificial dyes, MSG, artificial sweeteners, carrageenan, artificial preservatives, hydrogenated oils, corn syrups, banned-abroad additives) share 60 points equally — not found earns a group’s full share, “may contain” earns half, listed earns 0; a verified organic claim is worth 25; a verified grass-fed or pasture-raised claim is worth 15 and counts only for animal foods. No claim, or an expired or unverified claim, earns nothing, so products without those claims cannot reach 100. Unverified or expired ingredient labels receive no score. Equal scores are equal. Ties are ordered by brand. Unknown and stale evidence never passes “Only show matches.” Producer claims and prices do not affect this score. This is not a nutrition, allergy, or safety rating.
