Maybe deprecate @wordpress/editor PanelColor?

[chrisvanpatten]

I'm working on some definitive documentation of color palettes in Gutenberg (revising/extending #7906), and in the process noticed that we have two versions of colour inspector panels inside the @wordpress/editor package right now:

PanelColor

• Code here
• Has a small CSS float bug w/ the clear button

PanelColorSettings

• Code here
• Nicely supports multiple colors
• No CSS float bug

Consolidate/deprecate?

Overall PanelColorSettings seems superior because of its support for multiple color values and for not having the clear button float issue. Since the two are so similar, does it make sense to deprecate and remove the less-powerful/visually-broken PanelColor and standardize on PanelColorSettings?

PanelColor also wrapped a component of the same name inside @wordpress/components which could also be deprecated/removed.

If desired, PanelColorSettings could also be updated to hide the smaller color name label if only one color "type" is set, which would more closely reflect the current look of PanelColor.

Curious to hear thoughts on this!

cc'ing @jorgefilipecosta since I know he's done a lot of work on color stuff!

Per convo on Slack it sounds like this was intended to be deprecated but was missed. I’ll see if I can work up a PR for this today... would be nice to get the deprecation warning into 4.0.
