Morphology
color + vision + deficiency
The noun phrase is transparently compositional: 'color' (hue) + 'vision' (ability to see) + 'deficiency' (lack) clearly yields a lack or impairment in perceiving colors. The meaning is directly inferable from the parts and aligns with common cross-linguistic expressions (e.g. 'colour blindness'), so a B1 learner who knows the constituents should understand it.
Etymology
Color vision deficiency is a simple, literal name: imagine a painter whose box of paints is missing some colours, so they cannot mix or see certain shades. So, the phrase means 'difficulty telling some colours apart', often called 'colour blindness'.
