Subtractive RG?[edit]

It would appear that there are several different RG color spaces, distinguished by how they handle blue as a function of red and green. The article describes additive RG, which sets blue to 0 intensity. But Image:Anna May Wong holds child in The Toll of the Sea.jpg doesn't appear yellow throughout. "Subtractive" RG would appear to set blue = red * green or the like. The form of RG used in some anaglyph images is actually red-cyan, setting blue = green. Is there a source for information about different RG spaces? --Damian Yerrick (talk | stalk) 19:11, 12 September 2007 (UTC)
