Morphology
red-green + dichromacy
The term is compositional: 'red-green' specifies the hues involved and 'dichromacy' denotes a two-color/limited-color vision condition, so the overall meaning (difficulty distinguishing red and green) follows directly from the parts. This modifier + medical-condition pattern is cross-linguistically regular and would be understandable to a B1 learner who knows the constituent words.
Etymology
Red-green dichromacy comes from the two colors red and green. It describes when a person's eyes cannot tell red and green apart, for example making traffic lights hard to read, so it means 'difficulty distinguishing red and green'.
