Phenotype: Colour Blindness

Colour Blindness is a optical disorder characterized by the inability to see one or more wavelengths of light.

The currently defined types of colour blindness (and therefore variables for this phenotype) are:

Total Colour Blindness: Inability to differentiate any colours, only differences in brightness

Red-Green Colour Blindness: Difficulty or inability to differentiate between red and green wavelengths

Blue-Yellow Colour Blindness: Difficulty or inability to distinguish blue and yellow hues apart

False: No known colour detection anomalies
