The Primary Purpose of Food Dyes in Soda
Artificial food dyes are added to soft drinks primarily for aesthetic reasons, not nutritional ones. They are used to create the vibrant, consistent colors that consumers associate with certain flavors, such as the bright orange of Sunkist or the deep brown of a cola. Manufacturers understand that people 'eat with their eyes,' and color is a critical part of the sensory experience that drives consumer preference. In the past, companies like PepsiCo have even marketed their products on the absence of such dyes. However, synthetic colors eventually won out due to their vibrancy, consistency, and lower cost compared to natural alternatives.
Common Artificial Food Dyes in Soft Drinks
Several specific synthetic dyes are consistently used across the soda industry. Knowing which ones are used in which products is key to identifying artificially colored sodas.
Red 40 (Allura Red AC)
One of the most widely used and recognizable synthetic colors, Red 40 is responsible for the red hue in many fruit-flavored drinks. It's often found in combination with other dyes to create a specific shade. In the United States, sodas containing Red 40 include:
- Mountain Dew Code Red
- Pepsi Wild Cherry
- Fanta Strawberry
- Jarritos Strawberry
- Some varieties of Dr. Pepper Cherry
Yellow 5 (Tartrazine)
Yellow 5 gives a bright yellow color to many citrus-flavored and tropical sodas. This dye is found in both regular and diet versions of some popular brands.
- Mountain Dew (gives it the signature bright yellow-green color)
- Diet Mountain Dew
- Some Fanta Soda varieties
- Some Sprite varieties (specifically special flavors)
Yellow 6 (Sunset Yellow)
Similar to Yellow 5, Yellow 6 is used to create orange and yellow tones in soft drinks. It's often paired with Red 40 for orange-flavored products.
- Fanta Orange
- Diet Sunkist Orange
Caramel Color (E150d)
The dark brown color of colas and root beers comes from caramel color, not naturally occurring ingredients. Unlike the caramel made in a kitchen, this artificial version contains chemicals like 4-methylimidazole (4-MeI), which has been flagged as a potential carcinogen. This dye is found in virtually all dark-colored colas.
- Coca-Cola
- Pepsi
- Dr. Pepper
- Diet Coke
- Diet Pepsi
- A&W Root Beer
Blue 1 (Brilliant Blue)
Used to create blue or green hues, Blue 1 is typically found in specialized soda flavors.
- Frostie Blue Cream Soda
- Some multicolored candies

Reading Labels and Identifying Dye-Free Alternatives
To avoid artificial food dyes, the simplest approach is to check the ingredient list. Look for words like 'Red 40', 'Yellow 5', 'Yellow 6', 'Blue 1', or 'caramel color'. Many soda brands now offer dye-free options, and some clear sodas are naturally without artificial coloring. It's important to remember that not all clear sodas are guaranteed to be dye-free, as some may contain other artificial additives.
Naturally Dye-Free Soda Options:
- Clear Sodas: Many lemon-lime sodas like Sprite (US) and 7-Up are clear and generally don't contain artificial dyes.
- Natural Brands: Newer, health-conscious brands like Olipop and Zevia use natural ingredients and avoid artificial colors.
- Ginger Ale: Most ginger ale brands are naturally colored without artificial dyes, using caramel color in some cases.
- Some Fruit Flavors: Certain flavors from Jarritos (like Guava, Mango, Tamarind, and Grapefruit) are dye-free, while others are not.
What About Natural Colors?
In response to consumer demand for cleaner labels, some beverage manufacturers have started using natural colorants derived from ingredients like paprika, turmeric, and beet juice. These natural colors offer a more wholesome alternative but may not always produce the same intensity and consistency as synthetic dyes. Consumers should still check labels to ensure 'natural colors' are the source of a soda's hue.
Making Informed Choices for a Healthier Diet
While artificial food dyes are approved by regulatory bodies like the FDA, concerns about their potential health effects persist, particularly regarding hyperactivity in children and other health issues. Making a conscious effort to choose beverages without artificial dyes is a dietary preference many people adopt. By understanding which sodas have food dye and which don't, you can select alternatives that better align with your health goals.
