colormap creation

Can someone please recommend a (semi) automatic way to create the rgb
dictionaries needed for colormap creation?
Basically, I have a 'general' idea of how I want my colors ordered, but Im
finding it difficult to create the smooth transitions by manually editing
the rgb dictionary for my custom colormap...the trial & error process is
tedious & not very accurate...

How were the matplotlib colormaps created?
Were they created manually or programmatically?
Was it done using a random color selection?

Please help,
Thanks,
P.Romero

P.R.: If you haven't already, you should look at the custom_cmap.py example.
