  • Discussion: This MEP has not commenced yet, but here are someongoing ideas which may become a part of this MEP:

Branches and Pull requests#

Abstract#

  • color

    • tidy up the namespace

    • Define a "Color" class

    • make it easy to convert from one color type to another`hex->RGB`,`RGB->hex`,`HSV->RGB` etc.

    • improve the construction of a colormap - the dictionary approachis archaic and overly complex (though incredibly powerful)

    • make it possible to interpolate between two or more color typesin different modes, especially useful for construction ofcolormaps in HSV space for instance

  • cm

    • rename the module to something more descriptive - mappables?

Overall, there are a lot of improvements that can be made withmatplotlib color handling - managing backwards compatibility will bedifficult as there are some badly named variables/modules which reallyshouldn't exist - but a clear path and message for migration should beavailable, with a large amount of focus on this in the API changesdocumentation.
