Eating lots of carrots will turn the pigment in your skin orange.
(Carotenaemia is the presence in blood of the yellow pigment carotene from excessive intake of carrots or other vegetables or fruit containing the pigment, which results in increased serum carotenoids. Strangely carotene is the same substance that makes leaves turn orange in the autumn. But you would have to eat a silly amount of carrots, and eating them in moderation will help your eyes!)
