Pink

Nintendo's Kirby was pink from the very start, but when Kirby's Dream Land launched in North America in 1992, staff copied his grayscale Game Boy sprite literally and drew him white. For years, North American box art, manuals, and ads all showed a white Kirby.

A flamingo's pink feathers aren't its natural color. Flamingos hatch gray; they turn pink as carotenoid pigments from the brine shrimp and algae they eat build up in their bodies. Without these pigments in their diet, their feathers fade back toward a pale white.
