Document Summary

Red apple does not have the quality of red . The ability to see in colour is not because the objects or surfaces themselves are inherently colourful. That is, colour is a creation of our minds. The subjective experience relates to how the different wavelengths of light affect certain cones in our retina. Colour obviously adds to the richness of our visual experience. (black and white forest scene is difficult for us to pick out individual tree, but with the colour scene, it"s much easier to tell the trees apart. ) Ex: when the matador takes off his red cape and waves it at the incensed bull who charges. Presumably, the bull charges because the flash of the red cape infuriated him. It turns out that bulls don"t see the cape as red, they just see a piece of grey, moving cloth. Many birds, fish, reptiles and insects have excellent colour vision.
