There are various types of skin darkening. One type is hyperpigmentation that occurs when certain skin cells release more pigment (dark color). Darkening of the skin due to  blueness  is called cyanosis (see also blue skin) or purple skin. Darkening may sometimes occur from redness or bruising.
Skin pigmentation disorders occur because the body produces either too much or too little melanin, a pigment that creates hair, skin, and eye color. Melanin protects the body by absorbing ultraviolet light. In hypopigmentation means the body does not produces enough melanin. Albinism, for example, is an inherited condition that causes a lack of pigment. So people with albinism typically have light skin, white or pale yellow hair, and light blue or gray eyes. Another condition called vitilgo, creates smooth, depigmented white spots on the skin.
