Originally posted by geniusAside from those who are inherently colorblind, I figure that the cones in one's eyes must perceive the hues within reason, identically. I believe that pantone colors can't work if the colors can be viewed differently by different people. Plus, there certainly would be a disconnect between different peoples, wouldn't there?
[...]and discussing pointless topics such as "what if what you see as red i see as green?" etc...)
Also, based upon light wavelengths, we already have an established standard for ROYGBIV.
And, I believe the aesthetics of an image (color wise, if not also content) must be universal as well. One would be hard pressed to look at, say, a sunset, and have the wavelengths of light be processed by the cones in any way but yellows, reds, and pinks, in proper arrangements.
Likewise, a tuning fork wouldn't work if sound frequencies were intercepted in the ear differently by person. Soundwaves and light waves must be processed accurately and consistently. It is easy to notice a piano that may be even slightly out of tune. Especially if you're familiar with the sound that is produced when the piano is in tune.
