Color Curves Quick Reference Guide

Thanks John Dickinson's Color Curves Quick Reference Guide....

One thing you need to keep in mind...color combine RGB...
Red(1,0,0) <> Cyan(0,1,1)
Green(0,1,0) <> Magenta(1,0,1)
Blue(0,0,1) <> Yellow(1,1,0)

So when your eyes tell you the image looks so yellow, or Magenta... you will know how to fix them base on RGB channel...
