It would be nice to have explanations and comparisons of the techniques that are employed for the current behavior and the new behavior. The color gradient criticism feels valid from an aesthetic standpoint but the problem seems to be that a simple linear interpolation doesn't provide the desired color properties. This raises the question as to what exactly are the desired color properties from a technical standpoint and when is each technique applicable. Say we changed all color interpolations from an interpolation in RGB space to HSV space (as I imagine the color gradients suggested are achieved), would this have any unforeseen consequences?
