Which colour follows the green signal at a puffin crossing?

A puffin crossing is a type of pedestrian crossing. There are also pelican and toucan crossings.

Rule 23 of the UK Highway Code states:

Puffin crossings differ from pelican crossings as the red and green figures are above the control box on your side of the road and there is no flashing green figure phase. Press the button and wait for the green figure to show.
