I said and I repeat that the rule of tincture arose naturally from the mechanics of human color and shape perception, which relies on lightness contrasts for shape recognition (this is experimentally proven and you can easily prove it to yourself just by setting the foreground and background of some text or symbol to colors of similar lightness and then to colors of different lightness). The rule of tincture is simply a formal codification of this psychophysical fact of human visual perception, and thus merely the explanation underlying the fact that so many people (many of which I assume have no training or conscious awareness of color theory rules) are commenting on how the colors on this figure look to have been combined "wrongly", because to their eyes they simply look wrong (because their visual system is having an uncomfortably hard time trying to tell apart the foreground shapes from their backgrounds).
Sure, every rule-breaking visual effect has its appropriate use in certain exceptional cases (just like dissonance does have its place in music). M.C. Escher's masterful breaking of every rule our visual system relies on to perceive perspective and orientation, so as to create amazing optical illusions of impossible objects, sufficiently proves this. But I and many more people do not find the visual chromatic dissonance created by this figure's breaking of the tincture rule to result in anything but an inappropriate gaudiness unbefitting the should-be-majestic nature of the King He-Man character.
