[Feature] Color Picker: Keyboard accessibility

[isidorn]

Refs: #31457

It is good that the color picker can be triggered via our "Show Hover" command, however after that you can not do any changes to it using the keyboard.
It should be possible to use the keyboard to navigate inside the color picker and choose colors appropriatly.

I would love to use the new color picker but I can't without keyboard support :-(
Would you accept a PR for this keyboard controller?

If so I'll make a proposal for the commands and approach...

@cleidigh Unfortunately you'll have to wait for @rebornix to return, he's currently on leave. But feel free to start crafting a PR which makes your life easier yeah! 👍

Any updates to this?

@rbenson
No update yet. Since accessibility is getting more more attention , I would assume this can get in the schedule sometime soon.

This should work when the Color Picker is triggered via Show Hover command the focus should be passed into the color hover. Once focus is there:

• left, right, up, down should move the color
• tab should allow to move focus to transparency

@rebornix might this be a good feature request for help-wanted tag? I am adding it and you can remove it.

Since the help-wanted tag is on now, can I possibly take a look into this issue @isidorn?

[isidorn]

@ShahzaibP I think yes. But it would be cool if @rebornix also gives his approval :)

[ShahzaibParacha]

Sure thing, I will wait for the approval!

[rebornix]

You are being kind, you don't need my approval for a contribution, go ahead ❤️
