RichText text colors

[lowlighter]

Hi 👋 !

Would it be possible to support text colors in the rich text editor ?
(Unless it's already possible ?)

Think you can build in custom elements in the rich text editor:

This would maybe also awesome if it is added in the default elements.

You can open up a PR if you got it working
