Only rarely does stool color indicate a possibly serious intestinal condition. Stool color is generally influenced by what you eat as well as by the amount of bile — a yellow-green fluid that digests fats — in your ...
Tinea versicolor. The overgrowth of fungus that causes tinea versicolor interferes with the normal pigment production of the skin. This creates an uneven skin pigment. Tinea versicolor (TIN-ee-uh vur-si-KUL-ur) occurs most frequently in teens and young adults. Sun exposure may make tinea versicolor more apparent.

Stool gets its typical brownish color from bile, which flows into the small intestine during the digestive process. If the liver doesn't produce bile or if bile gets stuck in the liver, stool will be light colored or white. Often the problem occurs in the tube that delivers the bile to the small intestine. This tube is the bile duct.
Eye color can range from very light blue to brown and may change with age. With albinism, the colored parts of the eyes, called the irises, usually don't have enough pigment. This allows light to shine through the irises and makes the eyes extremely sensitive to bright light. Because of this, very light-colored eyes may appear red in some lighting.
