Did you ever notice anything about the impressive array of actors who voiced the colorful M&M spokecandies?
... the cynical and sardonic Red (originally voiced by Jon Lovitz, thereafter Billy West) who is the mascot for milk chocolate M&M's, and the happy and gullible Yellow (originally John Goodman, thereafter J.K. Simmons), who is the mascot for peanut M&M's. Other mascots include the "cool one", Blue (Phil Hartman, thereafter Robb Pruitt) who is the mascot for almond M&M's; the seductive Green (Cree Summer), who is the mascot for dark chocolate M&M's; and the slightly neurotic Orange / "Crispy" (Eric Kirchberger) for crispy M&M's. Green was the only female M&M's mascot until the businesslike Ms. Brown (Vanessa Williams), the "Chief Chocolate Officer," was introduced during the 2012 Super Bowl. [source]
