 ### Enhancements
 
+-   Default `--wp-admin-theme-color` to `#3858e9`, the WordPress 7.0 default admin color scheme, instead of the legacy `#007cba`. To keep the old color, include `admin-scheme(#007cba)` on `:root` in your own stylesheet. `wordpress-admin-schemes()` and the default custom properties now set `#007cba` for the Fresh scheme, which had used the `:root` default ([#83749](https://github.com/WordPress/gutenberg/pull/83749)).
 -   `radio-control`: Use the design system color tokens ([#83270](https://github.com/WordPress/gutenberg/pull/83270)).
