I have put a color label on three folders.
But how can I put them back?
I have tried [STOP TO MATCH] and [RESET].
But the folders remain colored.

You probably used Preferences / Labels / Label Assignments or Preferences / Labels / Label Assignments / In Specific Folders.

Delete or deactivate whatever you defined there.
