Morphology
trichromat = tri + chrom + at
The parts tri- (three) + chrom- (color) combine in a predictable way, but 'chrom-' is a technical combining form that many B1 learners may not know, so the meaning is not fully transparent to an average learner.
Etymology
The word trichromat comes from Greek roots tri- 'three' and chroma 'color', like triangle for three and chrome for color. So a trichromat is a person or animal who sees color with three types of color cells, which is why they can tell many shades apart.
