Morphology

chromogenic = chromogen (opaque) = chromogen + ic

The term is technical and built from Greek combining forms ('chromo-' and '-genic' / 'chromogen') that are unlikely to be known to an average B1 learner.

Etymology

Chromogenic comes from the Greek root chroma meaning 'color' and the part -genic meaning 'producing', as in the word 'photogenic' or 'generate'. So chromogenic literally means 'producing color' and is used for things like bacteria or photographic chemicals that make or develop color.
