What is the rarest M&M color?

M&Ms were first released in 1941, and since then have had an oversized impact on American popular culture.

M&Ms were inspired by rations given to soldiers during the Spanish Civil War. During World War II, they were exclusively sold to the U.S. military.

It became the first candy to rocket into space in 1981.

There are tons of different varieties of these popular Mars candies, with more flavors and ideas coming out regularly, the main staples have had the same colors for decades — red, green, yellow, orange, blue, and brown.

SAS Software company claims to be the largest corporate consumer of M&M's. As such, they used their own software to determine the proportions of colors within a bag of M&M's, and their findings were quite surprising. According to SAS, in 2008, Mars released the current color proportions within a bag of M&M's as, "24% blue, 20% orange, 16% green, 14% yellow, 13% red, 13% brown." This different from even 10 years earlier, in 1997, when the company said the rundown was "30% brown, 20% yellow, 20% red, 10% orange, 10% green, and 10% blue."
