There doesn't seem to be any predefined functionality for this. The
easiest way to achieve this is probably just to take the definition of
hsv from _cm.py and modify it a little:
data = {'red': ((0., 1., 1.),(0.158730, 1.000000, 1.000000),
(0.174603, 0.968750, 0.968750),(0.333333, 0.031250, 0.031250),
(0.349206, 0.000000, 0.000000),(0.666667, 0.000000, 0.000000)),
'green': ((0., 0., 0.),(0.158730, 0.937500, 0.937500),
(0.174603, 1.000000, 1.000000),(0.507937, 1.000000, 1.000000),
(0.666667, 0.062500, 0.062500)),
'blue': ((0., 0., 0.),(0.333333, 0.000000, 0.000000),
(0.349206, 0.062500, 0.062500),(0.507937, 1.000000, 1.000000),
(0.666667, 1.000000, 1.000000))}
for k,v in data.items():
data[k] = [(a/0.666667, b, c) for (a,b,c) in v]
myhsv = matplotlib.colors.LinearSegmentedColormap('myhsv', data)
