1911 Amer. Jrnl. Psychol. 22 370 It is now customary..to distinguish two groups of anomalous trichromates, upon the analogy of the two groups of dichromates,—the red-anomalous or protanomalous trichromates, whose sensitiveness to red is below normal, and the green-anomalous or deuteranomalous trichromates, whose sensitiveness to green is below normal.
1940 Proc. Physical Soc. 52 464 This result is difficult to reconcile with the ordinary conception that different degrees of protanomalous defect arise from the magnitude of the red response varying from one observer to another.
1975 Sci. Amer. Mar. 172/3 Some have considered that the protanomalous need more red in their mixture because, although they have normal cone pigments, the red signals are too weak.
1996 Occupational Med. 46 114 Red/green dichromats (protanopes and deuteranopes), severe deuteranomalous trichromats.., and protanomalous trichromats are unsuitable for firefighting work.
