THSLColor.DistanceSquared Method
Returns the distance between 2 colors. Not that this is not the euclidean distance, but a distance calculated to improve Hue matching. When converting cell colors, we try to preserve hues, so even a very pale red cell will be converted to bright red and not white or a very pale blue. This make it different from standard color matching as is done when adjusting images to a color palette, and where hue is not as important as here.
