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
