This is the closest thing we have to documentation for the new editor. It is a slight variation on the default editor for MediaWiki 1.33 so there may be more details on the general MediaWiki site. In short, it is just VisualEditor. It has a source mode but there is no separate source editor.

Coupling a basic editing mode with a buggy (historically speaking) visual editor has certainly caused discomfort for a lot of power users; at least the ones here on Community Central. Unfortunately, it seems we don't have a choice in the matter.

As for the text coloring, I assume that is analogous to the legacy platform's syntax highlighting. It is possible you aren't familiar with it if you keep it disabled like I do. Currently, there does not appear to be an option to disable it. I asked in the updates thread if such an option will be added and I have yet to receive a reply.
