If we're going to get technical, let's toss in color spaces. This is the part of the infinite, arbitrary RGB space that the {human eye | camera sensor | image file | output device} can {resolve | display}.

I view coins on several monitors, and each gives a different color presentation. I don't trust any of them, so I just make sure that my images are properly white balanced. If someone tells me my colors are "off", I am confident they are simply viewing with a monitor that is not well calibrated.

Well my whinging about it has been due to being caught out nastily.

I printed some posters of coins the gold coins came out OK but the silver had a yellow cast. I had been using my lap tops screen and on it the posters had looked the correct color. Now with the old screen connected the yellow cast is obvious. I now have the two screens operating at the same time.
