Dark skin gives seven to eightfold protection against DNA damage, but even the darkest skin colour cannot protect against all damage to DNA. Dark skin offers great protection against UVR because of its eumelanin content, the UVR-absorbing capabilities of large melanosomes, and because eumelanin can be mobilized faster and brought to the surface of the skin from the depths of the epidermis. For the same body region, light- and dark-skinned individuals have similar numbers of melanocytes (there is considerable variation between different body regions), but pigment-containing organelles, called melanosomes, are larger and more numerous in dark-skinned individuals.

Pigment pigment derived from a parasitic insect found in Central and South America—attained great status and value in Europe. Produced from harvested, dried, and crushed cochineal insects, carmine could be—and still is—used in fabric dye, food dye, body paint, or—in its solid lake form—almost any kind of paint or cosmetic. According to Diana Magaloni, the Florentine Codex contains a variety of illustrations with multiple variations of the red pigments. Specifically in the case of "achiotl (light red)," technical analysis of the paint reveals multiple layers of the pigment although the layers of the pigment is not visible to the naked eye.
