Two people see the same...........becozz.^


The cells in our retina, called photo receptors, are generally sensitive to what we call blue, green and red colors. It is actually more accurate to say that these photo receptors are generally sensitive to short, medium and long wavelengths because, as you suggest, what one person calls "red" may have different physical properties than what another person calls "red".
