Understanding Digital Color.

"For a correct exposure you want all the channels in all parts of the photo to be below the point they max out and loose detail. As a starting point you need to set the color balance of the camera to match the color of the light so when a bright white object is photographed all three channels will max out at exactly the same rate."
"That is referred to as setting the "White Balance" because white and all neutral gray tones are produced by a equal parts of Red, Green and Blue. When the color balance is out of sync some odd things will happen to very colorful areas in the photo."
