All this reminds me of a line from the end of "Driving Miss Daisy"...

"How you know how I see less'n you can look out my eyes?"

Everyone's perception of color is slightly different. Everyone's monitor displays color slightly different. Everyone has a different personal preference of what's the "right" color of something.

Bottom line is that no matter how finely Ady tunes the colors, someone isn't going to like it for some reason. When he finally releases it and you're playing it on your TV, if you think the colors aren't right, that's your problem, not his. Adjust the settings on your TV and make a preset for it.
