Chameleon

* Its color changes more or less with the color of the objects about it, or with its temper when disturbed. In a cool, dark place it is nearly white, or grayish; on admitting the light, it changes to brown, bottle-green, or blood red, of various shades, and more or less mottled in arrangment. The American chameleons belong to Anolis and allied genera of the family Iguanidæ. They are more slender in form than the true chameleons, but have the same power of changing their colors.

Chameleon mineral (Chem.), the compound called potassium permanganate, a dark violet, crystalline substance, KMnO₄, which in formation passes through a peculiar succession of color from green to blue, purple, red, etc. See Potassium permanganate, under Potassium.
