Heck, do we sighted folks even see the same colors in our brains... is the red I see in my mind the same color you see for red?

Sure we know colors have a particular wavelength, and the eyes respond in a certain way, but do our brains interpret that "input" in the same manner?

People universally believe that objects look colored because they are colored, just as we experience them. The sky looks blue because it is blue, grass looks green because it is green, and blood looks red because it is red. As surprising as it may seem, these beliefs are fundamentally mistaken. Neither objects nor lights are actually ‘colored’ in anything like the way we experience them. Rather, color is a psychological property of our visual experiences when we look at objects and lights, not a physical property of those objects or lights. The colors we see are based on physical properties of objects and lights that cause us to see them as colored, to be sure, but these physical properties are different in important ways from the colors we perceive. (Palmer 1999, p. 95)
