What color pigment does Eumelanin refer to?

Black to brown
Red to blonde
Blue to green
Pink to yellow

The correct answer is: Black to brown

Eumelanin refers to the brown to black pigment that is responsible for giving color to hair, skin, and eyes. This pigment is produced by cells called melanocytes. Red to blonde (option B), blue to green (option C), and pink to yellow (option D) are incorrect because these colors are produced by other types of pigments, such as pheomelanin and carotenoids. Eumelanin is the most common pigment found in humans, and it is influenced by genetic factors, which is why some people have darker or lighter shades of hair, skin, or eye color.
