I had this very problem as a child. Later I learned that there are visual pigmenst that absorb different ranges of light wavelenghts, so I figured that green is green and red is red. Then I learned more about the brain and how it interprets information. There is no law saying that electromagnetic inputs HAVE to be interpreted visually, and actually, the infra-red is interpreted as heat. It has been speculated that dogs, for instance, might (and perhaps do) interpret smells as colours. Who knows? I am just an evolutionary biologist, but I am sure some cognitive neuroscientists has devoted his/her intire life to that problem.
