Figma doesn't specify per-state colors (hover/active/focus), and the button color doesn't change between states in Proton, so I made the search mode switcher button color unchanged across states. If it should change per state, let me know!

Thanks Daisuke, the Components Figma does show different states for the switcher: default, hover, active, and focused. See the "Searchmode Switcher" card here (hope this is the right link): https://www.figma.com/design/PqfaOcMGbX5liEXTTUzeYX/Nova-Components--Experimental-?node-id=538-30073&m=dev

Each state uses a different member of the token group for its background color, e.g., .

However, the chevron and "X" have the same color in all four states afaict: . I've asked Jessica in a Figma comment if that's correct. I guess we should wait and see what she says before continuing with this patch.

If you want to fix the background color for each state as part of that patch, feel free. Otherwise could you file a new bug please?

Oh, thank you very much!
I will update the background now, then wait for the X color.

I talked with Jules and they have a large tokens patch in D306443 that fixes this bug, the bg color per state, and multiple other things. It's still marked WIP but hopefully we will end up taking it, and if so, we can abandon this revision. Thanks for your work on it Daisuke!
