This hue is inspired by the bright yellow shell of the Yellow M&M, the cheerful color that has long stood out in the candy’s classic mix. Its warm, glossy tone evokes sweetness and simplicity—qualities embodied by the Yellow M&M character himself, a lovable, slightly goofy figure whose wide-eyed optimism has become a staple of the brand’s ads. Together, the candy and its mascot have made this sunny yellow one of the most instantly recognizable colors in the M&M world.
