Is colour a property intrinsic to light, or defined by our perception, the result of complex neural processing of the signals received by the retinal light receptors…
…a question like this makes me value the way questions are written in Spanish, enclosed in question marks, like quotations are enclosed in quotation marks…

Professor Stephen Westland has a very interesting article The Rays are not Coloured where he presents his observations of colour perception, how colours can be perceived differently depending on the spatial colour distribution of a pattern.

I’ll write some wise things after I finish reading the Feynman Lectures on Physics (vol.1 chapters 35 and 36 on Color Vision)… ¿wait a minute, why is the color sensation dealt with in a Physics textbook if colour is not a physical property of light waves?…
