Description

As part of the eleventh call for testing for the FSE Outreach program, an issue was found with using custom color palettes:

custom palette colours could not be applied globally, e.g. to all the headings, though the theme defined colours did work when applied globally. The custom palette colours did however work when applied to individual blocks.

When testing this further, I found that they don't seem to work at all, either globally or for individual blocks.

Step-by-step reproduction instructions

1. Open up the Appearance > Editor (beta)
2. Open up global styles.
3. Go to the Colors section.
4. Add a custom color to the color palette.
5. Try applying them to various parts of your site (background, text, etc). Notice no changes.
6. Try selecting an individual block like the Post Title block and apply a custom color palette. Notice either no change (Post title block doesn't change) or some blocks do change (Site Title does change)
