Morphology

blue-blindness = blindness (transparent) = blue + blind + ness

The noun is formed by prefixing 'blue-' to the existing noun 'blindness', yielding a clear meaning of difficulty perceiving blue hues.

Etymology

Blue-blindness is simply blue + blindness, where blindness means 'not able to see', so it literally means being 'blind' to blue. That's why the condition makes it hard to tell blue from yellow or similar colors.
