Artificial food colors are everywhere.
Pick up almost any food or drink at the store, and you’re likely to see something like, “FD&C Red No. 40 or FD&C Yellow No. 5” somewhere on the label.
But there is one place that I often run into artificial food colors that always catches me off guard; vegan recipes.
Not only are these chemicals toxic, but they also aren’t without cruelty.
Artificial Food Colors + the Animal Testing Connection
First of all, artificial food colors undergo animal testing.
I know; I felt the same way.
It’s not something I would have thought to check either. But, I was curious how companies make artificial food colors.
So I looked it up.
Guess what? They are a product of the wonder of chemistry and the industry of oil drilling.
Most importantly, not something I want on my vegan cupcakes. Gross.
Why Do We Need Artificial Food Colors?
Artificial colors keep food sitting in warehouses and on grocery shelves fresh and cheery looking so that we’ll buy it thinking how good and tasty it must be.
Likewise, and perhaps more insidiously, the bright rainbow colors of candy and drinks lure children with promises of a tasty delight.
These impressionable experiences can have associations that persist well into adulthood when decorating cakes and cookies.
If you need an example, look at how many websites there are devoted to perfectly decorated food, for instance.

The Marketing of Artificial Food Colors
Have you ever noticed that the grocery stores always put artificial food colors on sale around holidays? It’s continuously advertised the many ways to incorporate these products into our diets.
I’ve seen select colors for drinks, baked goods, or even ice cubes, for goodness sake.
All in the name of “fun.”
But why? Colors don’t add flavor to our food; that is to say, they taste pretty damn bad.
Is sheer fun worth the lives of animals?
Food Additives & Animal Testing
Believe it or not, animal testing is a common way to determine the safety of these chemicals before being used as a food additive.
Frankly speaking, these tests do not indicate their effect on humans. Instead, they determine the amount needed to cause cancer and death in the animals.
Let’s take a closer look at what goes into getting bottles of artificial food colors to grocery store shelves.
#1. FD&C Blue No. 1, Brilliant Blue FCF
- Tested on animals such as mice, rats, and dogs. Beagles were fed Brilliant Blue FCF for periods up to one year to determine the maximum amount of chemical one could ingest before it caused death. (1)
- Previously banned in Austria, Belgium, Denmark, France, Germany, Greece, Italy, Norway, Spain, Sweden, and Switzerland, among others but is “certified safe” as a food additive in the European Union and the United States. It causes allergic reactions in humans, particularly in people with pre-existing conditions. (2, 3)
#2. FD&C Blue No. 2 – Indigo Carmine
- Tested on animals such as mice, rats, and dogs. “Accidental ingestion of the material may be harmful; animal experiments indicate. . .may be fatal or may produce serious damage to the health of the individual.” (4)
- Indigo Carmine is a synthetic replacement for plant-derived indigo, often used as a textile dye. It’s also used in OTC capsules and accepted for food use even though it is harmful to the eyes, skin, and respiratory tract. (5, 6)
#3. FD&C Green No. 3 – Fast Green FCF
- Tested on animals such as mice, rats, and dogs. Beagles were fed Fast Green FCF for two years to determine its effects at high-levels of ingestion. Here’s a hint, it’s many. (7, 8)
- Fast Green is also an eye, skin, and lung irritant. It even has its very own Material Safety Data Sheet complete with health advisories. A little scary, right? (9)
#4. FD&C Red No. 40 – Allura Red AC
- Tested on animals such as mice and rats. In one test, rats were impregnated and fed doses of Allura Red AC. Before the mice and rats gave birth, researchers killed the animals. Then, they performed c-sections to study the fetus’s skeletal or soft tissue remains. (11)
- Red; it’s one of the most-used artificial colors in candy. It’s been found to cause behavioral & developmental problems in children. Also, it’s a carcinogenic & mutagenic azo dye. In short, it causes cancer growth in cells. (12, 13, 14)
#5. FD&C Red No. 3 – Erythrosine
- Tested on animals such as mice and rats. “. . .studies revealed an increased incidence of thyroid follicular cell hyperplasia and adenomas in male rats that received. . .FD&C Red No.3. . .during life-time following. . .exposure.” In other words, it gave the rats tumors and initial stages of cancer. (14)
- Similarly, this azo dye is what is known as a toxic endocrine disruptor which means it destroys normal hormone function. (15, 16)
#6. FD&C Yellow No. 5 – Tartrazine
- Tested on animals such as mice and rats. From one study, “. . .rats were deprived of food, but not water, and then blood samples were collected. . .Animals were then killed. . .” (17)
- Yellow No. 5 is a human health hazard. (18, 19)
#7. FD&C Yellow No. 6 – Sunset Yellow FCF
- Tested on animals such as mice, rats, and rabbits. Researchers put Sunset Yellow in petrolatum or in water solutions studied and found. . .[it to be an] irritant to rabbit eyes. (18)
- Yet another azo dye. Consumer advocates have petitioned the government to ban it, citing studies that found they increase hyperactivity in children. (19, 20)
More Artificial Food Colors
The seven listed here aren’t the only ones out there.
Citrus Red 2 is approved for one use only in food, to color the peel of oranges.
If you ask me, that’s a pretty big vegan conundrum, considering that it, too, is tested on animals.

Updates to This Article
I see some of you saying, “at some point, everything was tested on animals,” as a reason to continue eating artificial food colors.
But I think this misses the vegan point.
It’s true; as vegans, there is so much we cannot avoid. Think medications, cars, or computers, for example.
Since I can’t avoid everything, I avoid everything I can.
Rejecting unnecessary synthetic chemicals disguised as food isn’t all that hard anyway.
To clarify, sometimes I use “chemical” when talking about artificial food colors.
Before you start to type me an angry comment about how the entire world is made up of chemicals! Water is a chemical! Chemicals are everywhere!
I hear you, I know.
My claim is not that all chemicals are inherently bad.
What I’m saying is: Artificial food colors are toxic, unnecessary chemicals that are tested on animals.
In conclusion, they can and should be avoided.
