How to let vector direction define quiver plot colors

I'm trying to plot some vector data in matlab using the quiver function (full disclosure, I'm actually using m_quiver from the m_maps toolbox).

What I want is to set each individual arrow color to be relative to its direction, e.g. north being red, south being blue. Is there a way to do this? I'm picturing something like the CData option with scatter plots!

Hi Aidan, Did you find something to do this? I am interested in the same sort of plotting.

I gave up... At the moment I'm just using quiver_mc (which is an awesome function) and letting the magnitude set the color. -Sorry!

Great! Although this seems to define colour by magnitude and not direction. My issue is the arrow directions are slightly unclear because of the density.

Hi Aidan did you find any solution for that? I will be thankful if you can help me with that
