"Common trip" simply means that either breaker tripping will open both conductors, i.e. both "legs" via a handle that ties both handles together. Color has nothing to do with it! In a 240V circuit breaker, both poles are designed to open simultaneously. If not (i.e. if only one pole opened, the other would remain closed presenting a life and/or fire hazard).
