Show inline previews for rgb hex color strings (LSP `textDocument/documentColor`)

Describe the feature

Show a color preview for languages like CSS and Tailwind.

VSCode has this, which it calls "color decorators":

JetBrains editors, such as PyCharm, take it one step further and provide a color wheel + picker that can be opened by clicking on the color preview. This allows you to change the color in a more human friendly way, while having the changes reflected in the source code in the original format.

I use a color highlight extension which enables different styles:

LSP can provide this via textDocument/documentColor.

This would be amazing. Is it in the roadmap?

Really important feature for me

This is a very important feature for FE devs as we tend to work with colors. Would appreciate if this is added 👌
