König (reference 25) proposed the designation, anomalous trichromatism, for the classes later designated separately by Nagel (reference 37) in an extension of the v. Kries terminology.
This extension of the v. Kries terminology was proposed by Engelking (reference 4).
This extension of the v. Kries terminology was proposed by Müller (reference 34, p. 68).
The term, alteration system, was proposed originally by v. Kries (references 27, 28, p. 408); Müller also uses Nagel’s terminology; see note 2.
The term, cone blindness, is based upon the duplicity theory of v. Kries and Parinaud, now widely accepted (reference 33).
Protanopic observers are sometimes called scoterythrous (reference 47), and deuteranopic, photerythrous.
Total color-blindness is often called achromatopsia (reference 49) or achromatopia.
