Eumelanin is a dark pigment that predominates in black and brunette hair. There are two different types of eumelanin (brown eumelanin and black eumelanin). A small amount of brown eumelanin in the absence of other pigments apparently causes blond hair. Pheomelanin is a lighter pigment found in red hair, and is concentrated in the redder areas of the skin such as the lips.
