We extend the Banados-Silk-West effect to the static spherically symmetric black hole and rotating black hole in gravity's rainbow. Through systematic investigation that the effects of different rainbow functions on the center-of-mass energy of two test particles colliding outside the event horizon, we discussed the possibility of infinite center-of-mass energy Ecm and the corresponding motion parameters. By employing rainbow functions g0=g1=(1-E/EP)-1, infinite Ecm can be achieved through collisions occurring outside the event horizon, rather than being confined solely to collisions near the event horizon.
