Hello,

Any ideas why I can't change color of the points?

I[1]: from enthought.mayavi import mlab

I[2]: r = np.random.uniform(0,5,size=[3,1,300])

I[3]: mlab.points3d(r[0],r[1],r[2], scale_factor=0.5)
O[3]: <enthought.mayavi.modules.glyph.Glyph object at 0xc48774c>

I[4]: ---------------------------------------------------------------------------

Trying to set the foreground via the GUI yields similar result:

TraitError: The 'foreground' trait of a MayaviScene instance must be a tuple of the form: (0.0 <= a floating point number <= 1.0, 0.0 <= a floating point number <= 1.0, 0.0 <= a floating point number <= 1.0), but a value of wx.Colour(255, 255, 255, 255) <class 'wx._gdi.Colour'> was specified.

Should be rev_25196
