From thinking about the ability to see color, it is apparent that the brain makes up much of what we interpret as characteristics of our environment. That is, we assume that objects have color, however this is false because it is actually the brain that asigns color to objects based on the wavelength of the light reflected. I then wonder if since everyone's brain is slightly different, could each person interpret the wavelengths differently so that the colors I see are different than those someone else sees. The only similarities are the names we assign to the specific wavelengths. Clearly, it can never be determined as a color cannot be described without relating it to another color.

Yes, it is certainly true that different people may have different internal experiences associated with "color" (as well as with other things). Which makes it all the more important that people share their experiences, with the objective of taking advantage of their differences to generate a larger "reality". PG
