What problem does this address?

Using theme.json is great progress in the efforts to standardize and streamline. However there is no one quick and easy way to see what is set in the theme.json as a user. I propose we look into creating a theme style guide. It would be a WordPress admin page that shows all the theme.json details in a more user pleasing manner. For example we could have a section showing all the colors created in the theme.json along with their names, and slugs. Yes users can use devtools, or edit a post and look at the choose colors control, but neither are great options (or obvious) if you want to read all the color names in an easy list format.
