What is the color coding on food packaging?

Food packaging often uses color coding to indicate different attributes about the product inside. This color coding is designed to quickly communicate information to consumers when they are shopping. Understanding what the different colors represent can help shoppers make informed choices.

Nutrition Facts Labeling

One of the most common uses of color coding on food packaging is for nutrition facts labels. The Nutrition Facts panel provides detailed information about the nutrient content of foods. While the format is standardized, the use of color draws attention to certain details.

Key parts of the nutrition facts label are often highlighted with color:

  • Calories are emphasized in larger or bolder text.
  • Percent daily values are colored, like reds for high percentages and greens for low.
  • Servings per container numbers stand out in a contrasting color.

These strategic uses of color help consumers quickly see the most meaningful nutrition numbers for comparing products.

Ingredient Lists

Color coding is also sometimes used on ingredient lists as another way to highlight important information.

Potential uses of color include:

  • Highlighting major food allergens like wheat, milk, soy, etc.
  • Calling out organic or non-GMO ingredients.
  • Distinguishing natural vs. artificial ingredients.

Again, the purpose is to direct consumer attention to the details that matter most to them.

Food Date Labeling

Expiration and freshness dating on packages are often color-coded as well. This helps shoppers quickly identify when a product may no longer be good.

Some common color coding systems for food date labels include:

Label Color Meaning
Sell By Red Store should sell by this date for peak freshness
Best Before Yellow Best flavor/quality if used by this date
Use By Green Recommended last date for use at peak quality

The visual cue of the color draws the consumer’s eye to the date label and its meaning.

Food Safety & Temperature Indicators

Color codes are also used on some packaging to denote food safety information. This includes indicators of proper storage and preparation temperatures.

Some examples include:

  • Blue fish icon – Indicates food must be kept refrigerated or frozen for safety.
  • Red meat icon – Signals meat must reach a safe internal temperature when cooking.
  • Thermochromic inks – Change color to show if food is above or below a safe temperature range.

These types of visual cues aim to reinforce proper food handling to reduce foodborne illness risks.

Dietary & Lifestyle Labeling

As special diets have proliferated, color coding has become a shortcut way to denote attributes like vegan, dairy-free, low FODMAP, keto, and more.

Some common examples include:

Icon Color Diet
V Label Green Vegan
Vegetarian Symbol Green Vegetarian
LF Icon Blue Lactose Free
GF Label Yellow Gluten Free

This labeling helps consumers with special dietary needs or preferences quickly identify appropriate products.

GMO & Organic Status

Non-GMO and organic status are two other attributes often called out with color-coded logos on packaging:

  • Non-GMO Project Verified – Orange butterfly logo
  • USDA Organic – Green & White logo

These seals assure consumers that products meet specific criteria regarding genetically-modified ingredients or organic production.

Grade Quality Labeling

Some products like meat, eggs, and maple syrup use color to denote official USDA grade designations. These communicate standardized quality levels.

Common examples include:

  • Beef – Red for USDA Choice, Black for USDA Prime
  • Eggs – AA in red, A in green, B in blue
  • Maple Syrup – Grade A in red, Grade B in blue

The color system allows buyers to quickly identify quality variances.

Flavored Varieties

Color coding is also sometimes used to distinguish between flavors or varieties of the same food item. For example:

  • Yogurts – Red for strawberry, green for green apple, orange for peach
  • Sports Drinks – Orange for orange flavor, green for lemon-lime, red for fruit punch
  • Candy – Red for cherry, pink for watermelon, brown for caramel, etc.

This can help consumers easily spot their preferred flavors when shopping.

Private Branding

Private label store brands also often use color coding for consumers to easily differentiate their products from national brands. Target using red and Walmart using blue are two examples.

Nutritional & Health Messaging

Color is sometimes used on the front of packages to call out specific nutritional attributes or health-related messaging.

Some instances include:

  • Green banners for “Natural” claims
  • Blue “High Protein” badges
  • Purple “Supports Immunity” labels
  • Orange “Low Sodium” icons

This eye-catching color blocking helps direct attention to the health or nutrition focused marketing messages.

Kids’ Packaging

Fun colors are very commonly used on kids’ food products to make the items more visually appealing. For example:

  • Cereals – Bright blues, greens, purples, and reds
  • Fruit Snacks – Neon oranges, greens, purples
  • Yogurts – Tropical pinks, bright blues, light greens

The exciting colors help grab children’s attention and convey a sense of fun.

How Consumers Use Color Coding

When used effectively, color coding on food packaging can benefit consumers in several key ways:

  • Simplifies shopping – Allows quick identification of products that meet dietary needs or preferences.
  • Saves time – Reduces need to read detailed labels for common attributes like flavors, nutrition facts, etc.
  • Avoids mistakes – Clear coding helps prevent selection errors like mixing up strawberry and green apple yogurts.
  • Enhances understanding – Visual cues convey complex details like safe food handling with simple color associations.

Overall, color coding aims to streamline the shopping experience and empower smarter purchasing choices.

Criticisms of Color Coding

While color coding on food packaging provides many benefits, some criticisms and concerns exist:

  • Can be inconsistent across brands – No universal color coding system exists.
  • Confusing for color blind shoppers – Difficult to interpret for those with color vision deficiencies.
  • Potential for deception – Colors may misrepresent quality or nutrition to sell products.
  • Information overload – Too many codes make labels cluttered and complex.

To address these issues, color coding must be applied thoughtfully and supplemented with other detailed labeling.

The Future of Color Coding

Looking ahead, we may see several evolutions in the use of color coding on food packaging:

  • Standardization – Industry-wide adoption of common color codes could reduce confusion.
  • Clean label focus – More color emphasis on whole, natural ingredients.
  • Sustainability cues – Green for eco-friendly or compostable packaging.
  • Technology integration – Digital links, scannable logos, etc. could provide more info.

Color coding has already proven its usefulness in communicating food packaging details efficiently. With some refinements, it can continue providing value to consumers in their purchasing decisions.


Color coding on food packaging serves an important function – to quickly convey meaningful information to shoppers. By highlighting details like nutrition facts, ingredients, freshness, dietary attributes, flavors, and more, strategic use of color helps streamline shopping and empower smarter choices.

While color coding has limitations and critics, overall it aims to distill complex product details down to simple visual cues. This Allows busy shoppers to interpret key information at a glance. Understanding common color coding conventions can make navigating the grocery aisles easier.
