Morphology

dichromatism = dichromat (transparent) = di + chromat + ism

Formed by straightforward suffixation from 'dichromat' (di- 'two' + chromat 'color'), indicating the condition or state of being dichromatic.

Etymology

Dichromatism comes from the Greek parts di- 'two', chroma 'color', and -ism 'condition'. So it literally means a 'two-color condition' and describes people who see or match colors using only two kinds of color sense instead of the usual three.
