Does this need any updated tests?

As every impl needs to change this is a breaking change

Does this need any updated tests?

There weren't any tests for this. I think there's no implementations for From objects into Color in Ratatui. There's crossterm::style::Color -> ratatui::style::Color but that test will only work for the crossterm backend.

As every impl needs to change this is a breaking change

This is strictly breaking but in practice I don't think it'll break code because Stylize is fairly new and people may have not had the chance or reason to implement it. In the past we've merged similar "strictly breaking but not breaking in practice" changes in patch releases. Thoughts?

Open to suggestions on making this protected.

Open to suggestions on making this protected.

No hard opinion on this, but I know that I hate seeing traits in other libs that I'd like to be able to implement even if they later change them in the lib, but can't because they're not exposed, so I'd lean towards just keeping it as is, and dealing with breaking changes in the usual manners (communicating when we can, being mindful of the changes, etc.)

[joshka]

Is this the correct version for this - likely 'unreleased' or 0.26.3

[kdheepak]

Ugh my bad.

[joshka]

Also - 0.26.3 was slated to be a bugfix / no breaking changes release tomorrow, to make it easy for broken apps to just be fixed without any changes required. (version spec 0.26.2 will actually use 0.26.3 automatically when resolving, but it won't use 0.27.0)

[kdheepak]

Should I revert this PR until 0.27.0?
