Morphology

color + blindness

The compound uses a straightforward metaphor: combining 'color' with 'blindness' signals being 'blind to color' — i.e., ignoring racial differences — so a learner who knows both words could plausibly infer a meaning like 'not seeing or considering race'. However, the phrase extends beyond the literal medical sense into a sociopolitical concept with critical nuance (masking systemic inequality), so the precise ideological sense and its evaluative implications are not fully predictable without prior exposure.

Etymology

Color blindness comes from medicine: the words color and blindness make a picture of someone who is 'blind' to certain colors and so cannot tell them apart. So color blindness means an inability to see or distinguish some colors.
