colorwheel.mws Colorwheel idea MAPLE's HUE-colors' don't work. So how to map the complex plane onto the faces of the RGB-color cube with preferrably only a few if/max, but no analytic function evaluations? Preliminary investigations. Another idea: Use a smooth approximation -- the cost is slower evaluation of the color values, the advantage is no trouble with prematurely evaluated Boolean expressions The first attempt -- using color to visualize convergence of Taylor and Laurent expansions.
