Question: Is it possible to change the colorfunction of complexplot3d

Currently, the argument is mapped to the HUE coloring scheme (I guess)

plots:-complexplot3d(z, z = -2 - 2*I .. 2 + 2*I, title = -ln(1/c) - ln(c), orientation = [-90, 0, 0])

This makes it difficult to distinguish the sign of the argument close to the positive real axis (just to give an example). To increase contrast I thought about alternatives: Linear ramping from 0 to 2pi from one color to another (similar to phase wrapped images) or a stepped color scheme (in pi/4 increments for example).

I tried color=argument(z/2/Pi) but this did work.

Please Wait...
