Most plain chocolate Halloween candy is already dye-free. Kit Kat, Snickers, Reese’s Peanut Butter Cups and original Tootsie Rolls are brown because of cocoa, not Red 40. The candy that carries synthetic dyes is the brightly colored stuff: candy corn, Skittles, Starburst, M&M’s, Dots and Tootsie Pops.
So if you want a dye-free Halloween, you don’t need a specialty store. You need to skip the rainbow candy and read one line of the ingredient list.
Here’s what’s in the common bags, what changed this year, and what the evidence actually says.
Which Halloween Candy Has Synthetic Dyes?
We checked the manufacturers’ own ingredient statements. In the US, synthetic dyes must be named on the label, usually as “Red 40,” “Yellow 5,” “FD&C Blue 1,” or as a “Lake” (for example “Red 40 Lake”).
| Candy | Synthetic dyes? | What’s listed |
|---|---|---|
| Kit Kat (milk chocolate) | No | No color additives |
| Snickers | No | No color additives |
| Reese’s Peanut Butter Cups | No | No color additives |
| Tootsie Roll (The Original) | No | No color additives |
| Brach’s Candy Corn | Yes | Yellow 6, Yellow 5, Red 3 |
| Skittles Original (standard) | Yes | Red 40, Yellow 5, Yellow 6, Blue 1, Blue 2 and their lakes |
| M&M’s Milk Chocolate (standard) | Yes | Red 40, Yellow 5, Yellow 6, Blue 1, Blue 2 and their lakes |
| Starburst Original (standard) | Yes | Red 40, Yellow 5, Yellow 6, Blue 1 |
| Tootsie Pops | Yes | Red 40, Yellow 5, Blue 1 |
| Dots | Yes | Red 40, Yellow 5, Blue 1 |
| Tootsie Roll Fruit Chews | Yes | Yellow 5, Red 40, Blue 1 |
Notice the Tootsie line. The original chocolate Tootsie Roll is dye-free. The fruit version from the same company is not. Brand names don’t tell you anything here. The ingredient list does.
Seasonal versions can also differ. Halloween-colored packs sometimes add dyes that the everyday version doesn’t have, and fun-size packs can carry different recipes than full-size bars. Read the bag you actually bought.
Candy Corn Still Contains Red 3
Brach’s lists Red 3 as the last ingredient in its Classic Candy Corn.
In January 2025, the FDA revoked authorization for Red No. 3 in food. It did this under the Delaney Clause, a 1960 law that bars approval of any color additive shown to cause cancer in humans or animals. High doses caused cancer in male rats. The FDA itself says the rat mechanism doesn’t occur in humans and that typical human exposure is much lower.
The deadline for food makers to reformulate is January 15, 2027. Until then, Red 3 is legal, and even after that date products made before the deadline can still be on shelves. In July 2025 the FDA wrote to manufacturers asking them to stop using it sooner.
If you want to avoid Red 3 this Halloween, candy corn is the main place to look. Red 3 also shows up in some frostings, cake decorations and frozen desserts.
What Changed in 2026
Three things moved this year.
Dye-free M&M’s, Skittles and Starburst exist now. In August 2026, Mars started selling versions of M&M’s, Skittles and Starburst made without FD&C colors, using beet juice, turmeric, spirulina and beta-carotene instead. At launch they were sold on Amazon, not in every store. The regular versions with synthetic dyes are still what you’ll find in most Halloween bags. Check the label for “colors from natural sources” or a list of plant names instead of numbered dyes.
Hershey has a date. Hershey says it is on track to remove FD&C colors from its US products starting in 2027, and is working on colors from spirulina, carrots, radishes and beets for Jolly Rancher, Twizzlers and Reese’s Pieces. For this Halloween, those products still use synthetic dyes.
The FDA is pushing the whole industry. In April 2025, HHS and the FDA announced a plan to phase out the remaining petroleum-based dyes (Red 40, Yellow 5, Yellow 6, Blue 1, Blue 2 and Green 3) and to revoke Citrus Red 2 and Orange B. That plan relies on voluntary industry action. The FDA keeps a public tracker of company pledges, and in February 2026 it approved beetroot red and expanded uses for spirulina extract as natural colors.
What the Evidence Says About Dyes and Kids
This is where honest answers matter, because both “dyes are poison” and “dyes are totally fine” overstate it.
In 2007, a randomized, double-blind trial published in The Lancet (McCann et al.) gave children aged 3 and 8 to 9 drinks containing a mix of artificial colors and a preservative. Both age groups showed increased hyperactivity on average compared with placebo. That study led the European Union to require a warning label on foods containing six dyes, including Red 40 (Allura Red), Yellow 5 (tartrazine) and Yellow 6 (sunset yellow): “may have an adverse effect on activity and attention in children.”
In 2021, California’s Office of Environmental Health Hazard Assessment (OEHHA) finished a two-year review of 27 clinical trials plus animal research. It concluded that synthetic food dyes are associated with adverse neurobehavioral outcomes in some children, that children vary in sensitivity, and that the FDA’s acceptable daily intake levels, which rest on studies 35 to 70 years old, may not adequately protect children’s behavior.
The FDA’s long-standing position is that most children have no adverse effects from color additives, but some evidence suggests certain children may be sensitive to them.
Put together: dyes don’t affect every child, the effect is modest on average, and some kids clearly react. If you’ve noticed a pattern in your own child, that’s a reasonable reason to cut back. Halloween is one of the highest-dye weeks of the year, so it’s an easy place to start.
Dye-Free Candy to Hand Out
If you’re stocking a bowl and want to skip synthetic dyes completely, these work.
Plain chocolate. Kit Kat, Snickers, Reese’s Peanut Butter Cups, Hershey’s milk chocolate bars and original Tootsie Rolls. Cheap, easy to find, no dyes. Check for nut allergies before handing out anything with peanuts.
Naturally colored candy. SmartSweets lollipops and gummies are labeled “no synthetic dyes” and also carry very little sugar (SmartSweets Lollipops list 0g added sugar per two pops). YumEarth makes organic lollipops, fruit snacks and chewy candy colored with fruit and vegetable extracts. Unreal makes dark chocolate peanut butter cups and gems with plant-based colors.
The new Mars versions. If you order ahead, dye-free M&M’s, Skittles and Starburst are an option for kids who want the familiar brand.
Non-food treats. Glow sticks, stickers and spider rings have no dyes in anything a child eats. A teal pumpkin on your step tells allergy families you have them.
Dye-Free Doesn’t Mean Low Sugar
This is the trap. Swapping Skittles for dye-free Skittles removes the dyes and changes nothing else. The sugar is identical.
A fun-size Kit Kat is dye-free and still has 7 grams of added sugar. Candy colored with beet juice is still candy. For kids aged 2 to 18, the American Heart Association recommends under 25 grams of added sugar a day, and none under age 2.

How to Spot Dyes on Any Label
- Go to the ingredient list, not the front of the bag. “Natural flavors” on the front says nothing about colors.
- Look for a color name followed by a number: Red 40, Yellow 5, Yellow 6, Blue 1, Blue 2, Green 3, Red 3.
- Look for the word “Lake” (Red 40 Lake, Blue 1 Lake). Lakes are the same dyes in a form that doesn’t dissolve, used in coated candy.
- “Artificial colors” or “FD&C colors” without numbers means synthetic dyes are in there.
- Natural colors are listed by source: beet juice, turmeric, spirulina extract, annatto, paprika, beta-carotene, vegetable juice.
