This is not exactly a duplicate of #63072, but the theme would need ​classes like what PR 2944 and PR 6082 have.

​GB52864 suggested creating the classes automatically for any classic theme instead of updating each theme individually.

This pull request adds a new function to dynamically generate CSS classes for the theme's editor color palette in the Twentynineteen WordPress theme. The function ensures that text, background, and border color classes are created based on the theme's defined color palette and applies them as inline styles.
