Hi all,

While working  on this IPython Notebook
 
http://nbviewer.ipython.org/github/empet/Math/blob/master/DomainColoring.ipynb<about:invalid#zClosurez>
I wanted to compare the visual images of the same complex-valued function
generated by the classical domain coloring method, using HSV, respectively
HSL color model.

Unfortunately there is no matplotlib.colors.hsl_to_rgb(array)  function,
only colorsys.hsl_to_rgb(h,s,l). The latter acts on each pixel and is time
consuming.

My question is, there is a special reason for which hsl_to_rgb is not
implemented in matplotlib.colors for arrays?
 I also looked in skimage.color
http://scikit-image.org/docs/dev/api/skimage.color.html and couldn't find
such a function.

Is there a package containing such a conversion?
Thank you!

Em
