Morphology

dichromasy = dichromacy (opaque) = di + chrom + asy

Although built from recognizable combining forms (di- + chrom-), the medical term and its suffix are not productive or familiar to an average B1 learner, so the relation to everyday words is not clear.

Etymology

The word dichromasy comes from the Greek parts di- 'two' and chroma 'color', like monochrome which means 'one color'. So, dichromasy is a condition where a person can match colors by mixing only two types of light instead of the normal three.
