But if I do that I might find more bugs! 😆 This should work I think? In [6]: to_rgba(('C3', 0.5))

PR summary
Currently if we do
we get the unhelpful error shown in #28434. I couldn't find any existing tests for
is_color_likeso added a few. In the process of adding tests, found thatis also broken (see #28436 (comment)), so fixed that too.
Closes #28434, since this fixes the reported bug. There was a suggestion there about supporting color sequences in
plotbut it seems like that would be difficult to do. If we do want to discuss it further it might make sense to open a separate feature request issue.PR checklist
