The unfinished color theme UI is available to play with:
The CSS, HTML tab is the existing “Site Customization” stuff. Better name ideas are welcome.
As the warning says, it doesn’t make any changes to the site. Stuff to do next:
- add a color scheme from a plugin
- asset pipeline stuff to include the custom colors
Also, what is a “Theme”? I imagine it’s a bundle that includes one (or more, but choose one?) color scheme, and CSS and HTML.
