color as we see it also depends on what wave length is falling on it,the the angle and many other factors
I have made a deep study of color,,and unknown to anyone who has a painting of mine,,the painting will show things within it only if viewd under the dame light conditions as the paint was applied to it,, thus sometime in just one painting there will be parts that got painted by candle light,,and others under ultra violet,, and yest others in different direction,,candesent or incandesent light
