Revoking an invite – should confirmation banner be red or green?

I'm working on a feature where a user can send/invite other people to their organization:

The user can opt to revoke the invite. Once this action has been done, I'd like to display a confirmation banner.

Since this banner is successfully revoking an intended action, should it be green? Part of me also thinks it should be red since it's removing someone which can possibly be done in error?
