In MNE we allow users to update the selector colors, and have:

        selector.rect.set_color(color)        selector.rectprops.update(dict(facecolor=color))

This now emits a deprecation warning from#20113, but it doesn't indicate how code should be migrated. I looked at this and#20558 and hoped / thought maybe I could find someselector.set_* orselector.handle_props or something to modify but I don't see anything. How should we update our code? (And it might be worth improving the deprecation warning to give some hints to anyone else who hits this issue.) Maybe with something like this?

selector.artists[0].set_color(color)

theartists[0] is theselector.rect. But this just seems like a hack workaround, and if there are properties held internally it will not "stick" so I'm guessing it's not the right idea...
