Brit.

/ˈkʌlə ˌblʌɪn(d)nᵻs/, U.S.

/ˈkələr ˌblaɪn(d)nᵻs/

Forms: see colour n.¹ and blindness n.

Origin: Formed within English, by compounding. Etymons: colour n.¹, blindness n.

Etymology: < colour n.¹ + blindness n. Compare German Farbenblindheit (1819 or earlier). Compare slightly earlier Daltonism n.¹

1. Defective colour vision characterized by an inability to perceive or distinguish between certain colours, typically occurring as an inherited condition. Also: complete absence of colour vision.Colour blindness usually results from the absence or dysfunction of one or more of the pigments normally present in the cones of the retina. Its most common form is deuteranopia, or green blindness, which was described by John Dalton (who was affected by the condition) in 1794 (recorded in 1798 Mem. Lit. & Philos. Soc. Manchester 5 i. 28; compare quot. 1798 for colour vision n. at colour n.¹ Compounds 4), and was for a time known as daltonism. Colour blindness has been considered by many scientists to be a misleading name, and a number of other terms have been proposed for the condition or its various forms, including achromatopsia, acritochromacy, dyschromatopsia, parachromatism, etc.; see also colour weakness n. at colour n.¹ Compounds 4.
