Document Summary

A single cone does not convey colour information it"s a combination of at least 2 cones depending of the wavelength (ration), the different cones will be differently activated adjusting intensity of a color can change your perception about it. Saturation add a bit a hue, add a bit a saturation. Add a lot of hue, add a lot of saturation. Colour is the result of the interception of light courses and material. Colours can be represented by combination of three primaries. Cones represent colours through ration o (cid:2) (cid:2) (cid:2) (cid:2) pairing of 4 primary colour : r g y b. Suggested spectrally-opponent channels: red vs green, yellow vs blues. Adapting to a light mixture of r, g ,y and b, would give rise to which. No adaptation (cid:2) (cid:2) after effect if you then look at a luminance matched grey background (cid:2) (cid:2) (cid:2) (cid:2) (cid:2) (cid:2) (cid:2)
