Monochromat (achromatopsia)


People with monochromatic vision can only see one colour, so their vision contains no 'colour'.

Typical monochromatic: unable to combine colours; fully grey scale; also known as rod monochromat.

Atypical monochromatic: very low colour recognition; also known as cone monochromat.


  

Dichromat


People with dichromatic vision use only two of the three visual pigments: red, green or blue is missing.

Protanopia: unable to receive red.

Deuteranopia: unable to receive green.

Tritanopia: unable to receive blue
