Map phase into color, or specifically hue. That is, map magnitude into L,
map phase into H, set S to 1.0 (or something close) and then convert
from HSL into RGB.

We did this and it sometimes worked. And sometimes didn't. Strongly
depends upon the sort of structures you are looking for.

Another to try is map magnitude into red and map phase into green. Some
shape information might come out better. Please note that the phase
map is circular to linear --- provide a rotation knob to alter the map
interactively to shift around the discontinuous point.

Good luck.
