Origin of metamerismmetamer + -ismChem. the type of isomerism in which chemical compounds have identical proportions of the same elements and the same molecular weight, but have radicals differing in type or position, with resulting differences in chemical properties
- Zool. the condition of being made up of metameres
(usually uncountable, plural metamerisms)
- (biology) The segmentation of the body into similar discrete units
- (colorimetry) The matching of apparent color of objects with different spectral power distributions.

metamerism - Computer Definition
(1) In colorimetry, the quality of some colors that causes them to appear different under various light sources. For example, two color samples might appear the same in natural light, but not in artificial light.
(2) In biology, repeating segments that appear the same but perform different functions. An earthworm is a common animal example.
