At a puffin crossing, which colour traffic light follows the green light?

Explanation: Puffin crossings have infra-red sensors that detect when pedestrians are crossing and hold the red traffic signal until the crossing is clear. The use of a sensor means there's no flashing amber phase, as there is with a pelican crossing; the lights follow the same sequence as traffic lights.
