Agouti coloring has bands of phaeomelanin and eumelanin on each hair. These banded hairs cover the head, back, and sides, giving these areas a ticked appearance. The eumelanin is completely removed from the underbelly, inner legs, chin, and at times, a line along the chin toward the ears, and an area around the ears leaving these areas red. The eumelanin is known as the base color and the phaeomelanin is known as the tip color.
