@matthew Unfortunately it is not possible to change the edit-boolean checkbox color in the current implementation of our object-tables. Please suggest the feature on our Public Roadmap so that we can start planning it for a future iteration.
@matthew We’ve gone ahead and added this request to our ProductBoard so no need to log the request on your side.
Alternatively, you may be able to achieve your desired result with cell-level actions and setting icon dynamically and then using style-icon-color to achieve something similar - rough draft example attached.
