Friedrich (or others), I hope you will consider the following to be constructive. I understand one use case for a gray switch: sometimes one needs to make gray versions of plots for formal publication, but one wants to have nicer color versions for other purposes. What is the use case for grayscale support for parts of the Figure? It seems to me that this requires a much more complex and extensive set of changes than a switch for the whole Figure. Is it really worth it? You indicate that some caching will need to be eliminated. Is this correct? If your branch causes a significant loss of speed in displaying and interacting with large data sets, then I will oppose merging it. Speed matters for a significant fraction of mpl usage. Improvements in mpl architecture that maintain or increase speed, and that make it more comprehensible, maintainable, and capable, are certainly welcome. Color handling has grown organically, often bedeviled by that pesky alpha, and I have no doubt that it could be cleaned up and improved.
