Morphology

dichromia = chromia (semi-transparent) = di + chrom + ia

The parts (di- 'two' + chromia 'color condition') give the general sense 'two-color condition', but the term is technical and uses Greek combining forms that many learners may not know.

Etymology

Dichromia comes from Greek parts di- meaning 'two' and chroma meaning 'color'. So, dichromia describes a condition where a person has only two working color types instead of three, which is why they can match all colors using only two kinds of light.
