At a puffin crossing, which colour follows the green signal?

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.
