Re: [Visualpython-users] color bar

I think you could achieve this effect with two (triangular) faces, whose 
vertices have different colors. See the documentation on faces.

If a cylinder would work, you could use a wide curve with many points 
and interpolate the hue along the path. Note that there are color 
functions for converting between RGB and hue-saturation-value (intensity).
