Normally skin coloration and skin pigmentation are dependent on the ethnicity of an individual. On many instances the normal human skin color gets changed in patches or in great areas due to many factors including environment, hormones, foods, immune responses and diseases. The following pages discuss individual skin discolorations and their causes.
Types of skin discoloration
Hypervascularization, inflammation or infections can cause red or pinkish color change in the affected area. Cyanosis, diet, hypercarotenemia, mineral overload, medicines and jaundice can also cause skin discolorations.

Color changes due to vitiligo are mostly brought about by autoimmune diseases causing death of melanin pigment producing cells (melanocytes). These hypopigmentation patches occur usually on the extremities like fingers. Color changes also occur around body orifices like umbilicus, mouth, genitalia, nostrils and eyes.

Dark brown or black discoloration of skin
Melanocytic nevus, commonly known as birthmark, is a common dark brown or black growth of the epidermis. Melanocytic nevus may form subdermally or form as a pigmented growth on the skin. Birthmarks are congenital being present at the time of birth and melanocytic nevi may appear in the later stages of life. Moles and birthmarks which change color, shape or size and those which are painful may have to be medically investigated as some can turn into melanoma (a type of cancer).

Reddish skin discoloration
When there is bleeding underneath the dermis purple or reddish discoloration change occurs which is known as purpura. Purpura does not blanch on applying finger pressure while erythema disappears. Inhalation of carbon monoxide can form carboxyhemoglobin in the blood giving reddish coloration. Carbon monoxide inhalation causes debilitating effects at low levels and is fatal in high levels.

Bluish discoloration of skin
Mongolian spots are due to melanocytes being entrapped and embedded deep in the dermis during their embryonic development and accumulation of melanin. Argyria is the bluish coloration due to accumulation of silver on the dermis caused by ingesting silver compounds as health potions.

Increased rate of breakdown of red blood cells can cause pre-hepatic jaundice. Hepatocellular jaundice is caused when the bile does not flow to duodenum. Post-hepatic jaundice is usually due to interruption to the flow of bile inside liver as well as to duodenum.

Nevus flammeus, a birthmark, produces reddened coloration due to dilation of superficial and deeper capillaries. Nevus flammeus usually persists throughout the life. Salmon patches (nevus simplex) are again highly prevalent birthmarks appearing on the forehead, eyelids, knees, on lips or back of neck. Salmon patches are due to dilation of superficial blood vessels and resolve as the child grows.

Orange skin discoloration
The coloration is more pronounced where the stratum corneum is thicker as in palms, soles and nasolabial folds. Secondary carotenemia occurs when there is decreased metabolism or excretion of carotenoids requiring medical treatment. Normally orange coloration resolves over a few days when excess consumption of carrots is stopped.
