color blindness
Cannot distinguish red
Color blindness is the inability to distinguish certain colors, most commonly red and green.
The condition is usually inherited and far more prevalent in men than women.
Complete color blindness—seeing only in grayscale—is rare.
Figuratively, color blindness means disregarding racial differences: The company claims color blindness in hiring.
Critics argue such claims ignore systemic inequalities.
