And what is not just a phenomenon of perception?

- magicalhippo 1y agoThe light hitting our eyes is not a phenomenon of perception. Each photon hitting our eyes has a certain wavelength, but the resulting color we see is a perception. A related concept is sound vs psychoacoustics[1]. Sound is just pressure waves, but what we hear is a perception and has all sorts of aspects like masking[2]. The pressure waves contains two different signals but thanks to masking we might only perceive one. Personally I think color constancy[3] really drives home that color is a perception and not something fundamental like the wavelength of photons.
