So basically how our eyes and brains work in relation to colour which we can call “the physiology of visual perception”Ī problem that came up was the colour yellow Helmholtz, another physicist who came op with the RGB model (the Young-Helmholtz theory) had stated that yellow came from a mixture of red and green (so there being 3 primary colours).įor hering this was not in line with the human experience because the sensation of yellow is very important and is not seen as a mixture of something else. Hering was a German physiologist who specialised in colour perception. ![]() I am going to explain to you Ewald Hering’s very exciting colour wheel chart containing of not 3 ( RGB) but 4 primary colours (RGBY). ![]()
