--random_colors not distinguishable

[giulia-berto]

When I visualize multiple tracts in .trk format with the flag --random_colors, it is hard to distinguish overlapping tracts since they have similar colors (in the case of 4 tracts, 2 are purple and two are green). It would be better to have distinguishable colors.

Thank you for the report @giulia-berto!

Can you have a look @Garyfallidis?

[Garyfallidis]

I think the distinguishable colormap is already being used when dipy_horizon is being called with random_colors but the randomization seed is fixed. Maybe you need to use a different seed.

[Garyfallidis]

Oh no. Actually we are not using distinguishable colormap. Will fix. Thanks for reporting.

Any update on this @Garyfallidis? Are you using distinguishable colormap with dipy_horizon?
