You’ve probably seen the headlines or the panicked TikToks. Someone holds up a bag of Original Skittles and claims they’re being banned because of a "toxic" chemical. It sounds like one of those internet hoaxes that pops up every few years, but this time, there is some actual legislative weight behind the noise. The conversation around red dye in Skittles has shifted from niche health food circles straight into the halls of government.
California recently passed the California Food Safety Act. It’s a big deal.
Basically, the state is banning four specific food additives, and one of them—Red Dye No. 3—is the reason everyone is looking closely at their candy wrappers. If you look at a bag of Skittles today, you might see Red 40 listed, not Red 3. But the confusion is real. People are wondering if their favorite fruit chews are safe, why the European versions look different, and if the "rainbow" is actually doing something to our brains.
The reality is a bit more nuanced than a thirty-second viral video. It’s about chemistry, lobbyists, and the slow-moving gears of the FDA.
The Drama Behind Red Dye No. 3
Let’s get the terminology straight because it matters. Most people talking about red dye in Skittles are actually conflating two different things: Red 40 and Red 3.
Red 40 is the most common food dye in the United States. It’s what makes your nacho cheese chips orange-red and your cherry soda pop. Red 3 (Erythrosine) is a bit different. It’s a petroleum-based substance that gives food a cherry-pinkish hue. Back in 1990, the FDA actually banned Red 3 in cosmetics and externally applied drugs because it was linked to thyroid cancer in rats.
Think about that for a second.
The government said, "You can't rub this on your skin, but you can definitely eat it in a maraschino cherry." That contradiction has lived on for over thirty years.
While Mars (the company that makes Skittles) has moved away from Red 3 in many products, the brand still finds itself at the center of the legislative crosshairs. The California ban, which takes effect in 2027, doesn't actually ban Skittles themselves. It just forces them to change the recipe. You’ll still get your candy; it just might use beet juice or pomegranate for color instead of a lab-created molecule.

Why Does Europe Have Different Skittles?
If you’ve ever bought a bag of Skittles in London, you might have noticed they look... duller. Sorta muted.
The European Union takes a "precautionary principle" approach to food safety. If there’s a reasonable doubt that a chemical might be harmful, they restrict it first and ask questions later. In the U.S., the FDA generally requires overwhelming proof of harm before pulling something off the shelves.
This creates a weird double standard.
Mars already makes a version of Skittles for the UK and EU that doesn't use these synthetic dyes. They use natural colors like curcumin, carmine, and chlorophyllin. So, when people say "Mars can’t change the recipe," they’re wrong. They already did it. They just haven't done it here because, frankly, synthetic dyes are cheaper and produce a more "electric" color that American consumers are used to.
The Science of Hyperactivity and Behavior
We have to talk about the "Red 40 makes kids crazy" theory.
It’s not just an old wives' tale anymore. While it doesn't affect every child, several high-profile studies, including a major one by the University of Southampton, suggested a link between synthetic food colors and increased hyperactivity in some children. This study was a big reason why the UK started requiring warning labels on foods with these dyes.
The California EPA’s Office of Environmental Health Hazard Assessment (OEHHA) conducted a massive review in 2021. They looked at 25 human studies and dozens of animal studies. Their conclusion? Consumption of synthetic food dyes is associated with adverse neurobehavioral outcomes in some children.
It’s not a 1:1 "eat a Skittle, get ADHD" situation. It’s more about sensitivity. Some kids' systems just don't process these synthetic molecules well.

Red 40 vs. Red 3: What’s Actually in the Bag?
Currently, Original Skittles in the U.S. primarily use Red 40 Lake, Yellow 5 Lake, Yellow 6 Lake, and Blue 1 Lake. The "Lake" part just means the dye has been mixed with a metallic salt so it doesn't dissolve in water, which keeps the color from bleeding into the white "S" on the candy.
Red 40 is still legal nationwide.
The confusion about the "Skittles ban" largely stems from the fact that Mars does use Red 3 in some of its other products, or has in the past. Even if Skittles specifically aren't using Red 3 right now, they are the poster child for the "Rainbow" of synthetic dyes that the public is starting to reject.
Is Red 40 safe? The FDA says yes, within "Acceptable Daily Intake" (ADI) levels. But the ADI was set decades ago. Critics argue that we eat way more processed food now than we did in the 70s. We're stacking these dyes. You have them in your cereal, your juice, your lunch snack, and your dessert.
A Quick Look at the Numbers
- Red 40: Made from petroleum distillates or coal tars. Permitted in almost everything.
- Red 3: Banned in the EU for most food uses. Banned in US cosmetics since 1990.
- Titanium Dioxide: This was another big one. It’s what makes the inside of a Skittle bright white. It was part of the original California bill but was eventually removed from the final ban after heavy lobbying, though it remains banned in the EU.
The Business of the Rainbow
Mars is in a tough spot. They’ve actually pledged to remove artificial colors from their food products globally years ago, but the rollout in the U.S. has been incredibly slow. Why? Because Americans like bright, consistent colors. If a Strawberry Skittle looks a little brownish because of natural fruit juice coloring, sales might dip.
But the tide is turning.
Retailers like Whole Foods have banned these dyes for years. Now, mainstream grocery stores are seeing a surge in "clean label" candy brands like Unreal or YumEarth. These companies use black carrot juice and spirulina to get those reds and blues.
Mars and other giants are watching California very closely. Because California is such a massive market, most companies won't make a "California version" and a "Rest of America version." It’s too expensive. They’ll likely just change the formula for everyone.

Is the Concern Overblown?
Honestly, it depends on who you ask.
If you ask a toxicologist, they’ll tell you that the dose makes the poison. Eating a fun-size pack of Skittles once a month isn't going to do much. But if you're a parent of a kid who struggles with focus, or if you have a personal sensitivity to petroleum-based dyes, the concern isn't overblown at all.
There's also the "why" factor. These dyes provide zero nutritional value. They are purely aesthetic. We’re essentially accepting a potential (even if small) health risk just so our candy looks more vibrant in the bowl. When you frame it that way, the push for natural alternatives seems pretty logical.
What You Should Do Now
If you're worried about red dye in Skittles, you don't have to wait for the government to act. You can make choices today that change how these companies operate.
First, start reading labels beyond the "Total Sugar" line. Look for "Allura Red" or "Red 40." If you see those, you're looking at a synthetic. If you see "Beet Juice," "Beta-carotene," or "Annatto," you're looking at food-derived color.
Secondly, understand that the "ban" isn't a "removal." Skittles aren't going away. They are evolving. The version of Skittles your kids eat in five years will likely be much closer to the version kids in France eat today.
Actionable Steps for the Conscious Consumer:
- Check the "S": If you want to avoid the controversial Red 3 specifically, check the labels on seasonal candies. Sometimes Valentine's Day or Halloween specials use different dyes than the standard year-round packs.
- Look for the "EU Version": Some specialty import shops sell UK-made Skittles. Try them. You’ll notice the flavor is often more "fruit-forward" because they aren't competing with the slight chemical aftertaste some people pick up from heavy synthetic dyes.
- Support Legislative Transparency: Regardless of where you stand on the ban, more transparency about what’s in our food is generally a win for the consumer.
- Monitor Personal Reactions: Keep a simple food diary if you suspect dyes affect your mood or your child's behavior. Many parents find that cutting out Red 40 leads to a noticeable "calming" effect within 48 hours.
The "Skittles controversy" is really just a symptom of a larger shift in how we view food in America. We're moving away from the era of "better living through chemistry" and back toward ingredients that actually come from the earth. The rainbow isn't going anywhere; it's just getting a makeover.
Stay skeptical of the viral panic, but stay informed about the ingredients. The more consumers demand cleaner products, the faster companies like Mars will bring those "European" recipes across the Atlantic. It’s not about losing your favorite candy—it’s about making sure that candy isn't carrying baggage it doesn't need.
