My problem seems to be less the coloring and more the geometry  :D

If I understand this correctly, you input a real, scalar angle, and get a
complex result out.  Then you plot the real part of f over the complex plane
described by z and the imaginary part of f?

Or is z actually x + iz, and your "3D" surface just a 3D slice of the 4D result
of your function - plotting the real or the imaginary part of f(z) over the x-z
plane?

And then you want to convert z to the H part of HSV and color <z, Re (f(z)), Im
(f(z))> according to that hue.

You are a masochist, a sadist, and a psychopath.
Much respect.  :D

I sent you an email - wondering if it arrived in inbox or spam.
