So first, I don't really have a strong opinion on this. But, when I think "palette", I usually think of a discrete one, as the artist's palette with a number of paint spots on it, rather than a linear one, which I would regard more as a color ramp. I don't have a strong enough opinion to argue forcefully for what is appropriate for PyX though, and will be happy to defer to the developers on this. That being said, though, I'd like to put the schemes in the code, and would like to know how I could do this. - First I need to make attr.changelists with names, not a problem. - Then I need to get permission, which I'm working on. It appears that the way we'd like to go is for the author of the schemes to license the schemes to PyX under the GPL; is that acceptable? - Next, how would you like them integrated? Separate file or at the end of color.py? And should I email them to you? - Finally, documentation ... how should these be exposed?
