The idea
Color blindness is reduced or absent discrimination between certain colors, usually from a missing or altered cone type.
In practice
A person with red-green color blindness distinguishes the two by brightness and position rather than by hue.
Where people slip
Most color blindness is partial. Seeing the world in grayscale is rare.
