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).
