Eh, that is not really accurate to how the color pie works. A person's color is defined by their very core characteristics and not what they would do in one episode. Hence why I place him at White/Blue through all incarnations because his core values are white/blue. It usually takes very large shifts in a character to change their color and even then it is usually shifting from a single to multi-colored, if anything the Regenerations would likely be Tri Color with the third dipping into how each regeneration shifts a little.
