In 1991, Peanut Butter M&M's were released. These candies have peanut butter inside the chocolate shell and the same color scheme as the other varieties. As of at least 2013, the size of the peanut butter M&M has become slightly smaller. In 1995, tan M&Ms were discontinued to be replaced by blue. To introduce the new color, the Home Shopping Network televised a promotional video for the blue M&M. Producer Jon Watson became the first man to wear the famous blue M&M suit.

The first incarnation of the characters in CGI was a 1994 celebrity campaign which had the characters interacting with celebrities on which M&Ms candy color is their favorite. This campaign was created by Blue Sky Studios. Concurrent with 1995's blue M&M campaign, M&M's introduced second computer-animated "spokescandies" in their television commercials. The depiction and campaign of the M&M's were made by Will Vinton in 1995. Vinton previously created the clay-animated California Raisins in 1986. Around the time he worked on CGI projects, he made the depiction of the M&M's as more mature than most food mascots. These include the team of the cynical and sardonic Red (originally voiced by Jon Lovitz, thereafter Billy West) [54] who is the mascot for milk chocolate, peanut butter, and crispy M&M's, and the happy and gullible Yellow (originally voiced by John Goodman, thereafter J.K. Simmons), who is the mascot for Peanut M&M's (he was originally known as "Peanut" when first introduced). Other mascots include the "cool one", Blue (voiced by Robb Pruitt) [55] [56] who is the mascot for Almond M&M's; the seductive Green (her personality is a reference to the 1970s urban legend that green M&Ms were aphrodisiacs) [57] (voiced by Cree Summer and Larissa Murray), [56] who is the mascot for both Dark Chocolate Mint and Peanut Butter M&M's, and the slightly neurotic Orange (voiced by Eric Kirchberger), who was introduced when Crispy M&M's were first released and returned when Pretzel M&M's debuted in 2010. Orange, upon his return, was joined by the second non-M&M mascot, Pretzel Guy, who "supports" him and offers helpful advice as he hates the idea of having a pretzel put inside his body. Celiac.com 09/16/2020 (Updated 03/15/2021) - M&M's candies do not advertise or label their products as gluten-free. However, with a few exceptions, their candies are gluten-free and safe for people with celiac disease. This list is for the USA, and note that in Australia and other countries they may contain wheat starch and not be gluten-free. The Nestle archives show [10] that George Harris of Rowntree and Forrest Mars Sr. agreed, after much negotiation, to share the marketplace rather than compete, with Rowntree making Mars Bars in Canada, Erie and South Africa and with Mars making M&M's in America without competition from Smarties, and Rowntree did not attempt to sue Mars for stealing their concept.
