Wright's (1952) tritan chromaticity coordinates

Data key


  1. Wavelength (nm)
  2. r(λ) chromaticity coordinate
  3. g(λ) chromaticity coordinate


Mean data from 7 tritanopes identified through the publication of Farnsworth's tritan test in the English journal, the Picture Post.

From Table II of Wright (1952). The individual data can be found in Table I(A-G) of Wright (1952).

These data and the tritanopic luminosity function can be used to construct the tritanopic CMFs--see Wright (1952).
