Mole Colors: What's Normal and What's Not

Moles (nevi) are pigmented skin growths ranging from light brown to dark brown or black. There is no such thing as a truly colorless mole. Any new, changing, or unusual lesion—especially if asymmetric, irregularly bordered, multicolored, large (>6 mm), or evolving—should be evaluated by a dermatologist to rule out melanoma.
