1911 Amer. Jrnl. Psychol. 22 371 Guttmann..identifies color-weakness with anomalous trichromacy.

1973 Vision Res. 13 2033 The condition of anomalous trichromacy thus includes the categories of simple and extreme protanomaly and simple and extreme deuteranomaly.

1980 Nature 27 Mar. 306/1 Our trichromacy has a ‘blue’ channel that is about 100 times less sensitive than the ‘red’ and ‘green’ channels.
