M&M’s candies are famous for their colorful candy shells, and each color has its own fun facts, history, and cultural associations. From the introduction of new shades to the popularity of certain colors in different countries, the story of M&M’s by color is surprisingly rich and filled with interesting details for any candy lover.
The Origin of M&M’s Colors
M&M’s were first introduced in 1941 with just two colors: brown and green. The original inspiration reportedly came from observing soldiers eating chocolate pellets with hard shells during the Spanish Civil War, which prevented the chocolate from melting. As M&M’s grew in popularity, Mars, Incorporated began to expand the color palette. By 1949, red, yellow, and violet were added. Over the decades, colors have come and gone, with the classic lineup now including red, orange, yellow, green, blue, and brown in the United States.
Color Percentages in Standard M&M’s
Many people wonder if all M&M’s colors are equally represented in a bag. The answer is no: Mars, Incorporated determines the percentage mix for each color, and it has changed over time. As of the most recent data available for milk chocolate M&M’s in the U.S., the approximate percentages are:
- Blue: 24%
- Orange: 20%
- Green: 16%
- Yellow: 14%
- Red: 13%
- Brown: 13%
These ratios can vary slightly depending on the production batch and the type of M&M’s (such as Peanut, Peanut Butter, or Crispy), but blue generally leads the pack since its introduction in 1995.
Retired and Limited-Edition Colors
Not all M&M’s colors have stood the test of time. Some were retired, while others appear only for special occasions:
- Tan: A staple for decades, tan M&M’s were replaced by blue in 1995 after a public vote.
- Violet: One of the original colors, but disappeared in the 1940s.
- Pink, Purple, Gold, Silver, and White: Sometimes appear in seasonal or custom batches, like Easter or wedding favors.
- Gray: Briefly produced for special marketing campaigns.
Special holiday mixes often feature only red and green (Christmas), pastels (Easter), or orange and brown (Halloween). The company also offers custom M&M’s in dozens of colors through their “My M&M’s” personalization program.
The Psychology and Popularity of M&M’s Colors
Color psychology and consumer preferences have played a role in M&M’s marketing and cultural impact. For example, in the 1970s, red M&M’s were temporarily removed due to concerns about the safety of Red Dye No. 2, even though M&M’s used a different dye. The red M&M’s returned in 1987 after consumer demand. Green M&M’s have gained a playful reputation in pop culture, often linked to urban legends about their supposed aphrodisiac qualities—a myth that Mars has gently poked fun at in advertising.
Blue M&M’s, the most recent addition to the regular lineup, became an instant fan favorite after their introduction in 1995, winning a nationwide vote. The popularity of blue led to its higher proportion in current mixes. Brown M&M’s are sometimes thought to be more “natural” because they resemble chocolate, though the shell is just colored sugar.
How M&M’s Get Their Colors
The process of coloring M&M’s is a feat of food engineering. After the chocolate is formed into spheres, it is coated multiple times with sugar syrup to build up the hard shell. The colored coatings are applied in layers using food-safe dyes—synthetic or, in some cases, naturally derived. The candies are then tumbled in polishing drums to achieve their signature gloss. Every M&M is stamped with the iconic “m” using a white food-grade ink.
In recent years, Mars has responded to consumer demand for more natural ingredients by experimenting with natural colorants, especially in European markets. For example, spirulina and turmeric have replaced synthetic blue and yellow dyes in some markets, although the U.S. standard mix still uses primarily artificial colors.
Specialty and International M&M’s Colors
Outside the U.S., M&M’s color mixes can differ. In Australia, for example, purple is part of the standard mix. In Japan, unique and sometimes limited-edition flavors and colors, such as sakura (cherry blossom) pink or wasabi green, have appeared. The “My M&M’s” program allows customers worldwide to order personalized color mixes, including black, teal, maroon, and more.
In addition to color, the flavor and filling can affect the color mix. Peanut M&M’s, for example, have a different color ratio than plain, and specialty varieties like Pretzel or Caramel may feature unique shell shades to distinguish them.
M&M’s Colors in Popular Culture
M&M’s colors have become iconic, appearing in everything from art to advertising. The anthropomorphic M&M’s characters—Red, Yellow, Green, Blue, Orange, and Brown—each have their own personalities in commercials and branding. Green, in particular, is often portrayed as sassy and confident, playing on her pop-culture reputation.
M&M’s colors have even influenced music and celebrity culture. The band Van Halen famously included a clause in their concert rider demanding all brown M&M’s be removed from their dressing room candy bowls, a request meant to check whether venues were following their technical requirements (and not, as some rumors suggested, out of color preference).
Frequently Asked Questions
- Are all M&M’s colors the same flavor?
Yes, for standard milk chocolate M&M’s, the color of the shell does not affect the flavor. The only exception is in special edition or flavored varieties, where the shell color may correspond to a specific taste. - What happened to tan M&M’s?
Tan M&M’s were discontinued in 1995 after a public vote that introduced blue as a new color. Blue quickly became one of the most popular colors in the standard mix. - Can you buy M&M’s in custom colors?
Yes, Mars offers a “My M&M’s” service where you can order M&M’s in a wide range of colors—including black, white, pink, and more—for events like weddings or corporate gifting. - Why are there fewer brown M&M’s now?
The ratio of brown M&M’s was reduced after blue was introduced, reflecting consumer preference and the results of popular votes. Brown now makes up about 13% of a standard bag. - Do other countries have different M&M’s colors?
Yes, countries like Australia and Japan feature unique color mixes and sometimes flavors not available in the U.S., such as purple or pink shells. - Are the dyes in M&M’s safe?
The food dyes used in M&M’s are approved by regulatory agencies like the FDA in the U.S. and EFSA in Europe. Some consumers prefer natural colors, and Mars has responded in some markets by using plant-based dyes.
Comparing M&M’s to Other Colorful Candies
M&M’s are not the only candy known for their bright colors. Skittles, Reese’s Pieces, and Smarties (the chocolate kind, not the American pressed-sugar variety) also feature colorful shells. However, M&M’s are unique in their use of a hard, glossy shell and the iconic “m” stamp. While Skittles’ colors usually correspond to different fruit flavors, M&M’s colors are purely aesthetic for the classic varieties.
M&M’s also stand out for their wide range of available colors in custom orders, making them a popular choice for parties and branding.
Fun Experiments and Activities with M&M’s Colors
The water-soluble dyes in M&M’s shells make them a favorite for simple science experiments. For example:
- Chromatography: Place M&M’s on a coffee filter with a few drops of water to see the colors separate into their component dyes.
- Color Mixing: Dissolve different M&M’s in water and combine the solutions to observe how colors blend.
These activities are popular in classrooms and at home, helping kids learn about chemistry and color theory in a hands-on way.
Tips for Choosing M&M’s by Color
If you want a specific color mix for an event, consider using the “My M&M’s” service or buying holiday-themed bags, which often feature only two or three colors. For standard mixes, blue and orange will be most abundant, while brown and red are less common. If you’re after rare colors like pink or black, custom orders are your best bet.
Conclusion: The Enduring Allure of M&M’s Colors
M&M’s colorful shells are much more than a decorative feature—they reflect decades of marketing, consumer preference, and even a little bit of pop culture history. Whether you’re sorting them by shade, searching for a nostalgic tan candy, or marveling at a rainbow of custom colors, M&M’s remain a playful and fascinating treat for all ages.
