An illustration of the Abney effect. The RGB primaries on a typical display is not monochromatic, making the effect weaker than the usual experimental setup. However, it is usually still possible to see the effect in the blue example.

Summary

Description
English: An illustration of the Abney effect. The RGB primaries on a typical display is not monochromatic, making the effect weaker than the usual experimental setup. However, it is usually still possible to see the effect in the blue example, with the middle shades appearing to be purple.

The mixing ratio step appears to be 10% in the gamma-corrected sRGB mixing system, but is in fact [0, 1.0022825574869039, 3.3104766570885054, 7.323895587840543, 13.286832155381797, 21.404114048223256, 31.854677812509184, 44.798841244188324, 60.38273388553378, 78.74122893956172, 100] in linear light. (A true 10% step would be appear too washed out.)
