1. Colorant - Pigments or dyes that are added in order to change or enhance the color.

An inorganic compound and a salt of chromium which is commonly used for its green pigment.

Chromium (III) oxide is relatively inert, and is the "dominant naturally occurring form of chromium". [1]

"In trace amounts, Cr is an essential component of animal nutrition, functioning mainly in glucose metabolism, and possibly in fat metabolism. While shown to be nonessential for plants, it is required by some microbes, possibly as a cofactor for specific enzyme systems." [2] Chromium (3+) is relatively non-toxic in general.

Chromic oxide is commonly used to determine the feed intake of animals via the determination of chromic oxide in feces. [3] [4]
