Has anyone tried to implement domain colouring in Plotly? Ie. using a colour scale to represent angle or anything else that rotates back onto itself. All of the predefined colour scales Plotly seems to have are used to accentuate peaks or valleys of data, having intensity in colour vary linearly with the scale. Does anyone have a quick, predefined colour scale they could point me to that resembles that of a colour wheel? (One that circles back to itself.)
@NatanTL I have defined a cyclical HSV colorscale, and used it for domain coloring, via Plotly, here:

This https://plot.ly/~empet/13977 is the visualization of a complex function on the Riemann sphere, with the same colorscale.
