True or False: Eumelanin gives hair its brown and black color.

Eumelanin is a type of pigment found in the hair, skin, and eyes, and it plays a crucial role in determining the darker shades of hair color, specifically brown and black. The presence of eumelanin is what leads to these darker colors, as it absorbs light and produces the pigmentation that characterizes brown and black hair. In general, the more eumelanin present, the darker the hair color will be. In contrast, the lighter colors, such as blonde and red, are associated with other types of melanin or lower concentrations of eumelanin. Therefore, stating that eumelanin gives hair its brown and black color is accurate.
