Hi, is there any colormap that can be used together with Julia Plots that encodes amplitude and phase of a complex field in a single color plot? E.g. hue encodes the phase and “lightness” or value the amplitude. Similar to this: Color map for complex numbers Thanks!

We have quite recently added a function complexColoring into the package ImageUtils. It colors complex arrays using a desaturation colormap. It is designed such that changes in phase do not alter its gray value. From the example posted this seems to be what you want. You can see the colormap in act…
