 ### Internal
 
+-   Remove the experimental color randomizer from the palette editor, along with the `colord` dependency it used ([#82452](https://github.com/WordPress/gutenberg/pull/82452)).
 -   Exclude the JavaScript tests and story from the build project so their declarations are not published. ([#81516](https://github.com/WordPress/gutenberg/pull/81516))
