Your saying that Dogs can see Prime colors that we can't? Hmn, do you think that there would be any way in the future to make humans see more colors then? that'd be awsome
Well, the primary colours are dependent on what type of receptors the eye has. Humans have red green and blue receptors, thus those are our primary colours.

I don't know what type of receptors dogs have, but I'm sure a quick Google check will clarify. However, I doubt that they would have special IR receptors. This means they will merely see IR as a deeper red.
