Single factor yellowface II typically has a buttercup yellow color to the face.

The body color for a single factor yellowface II after their first molt will change to a sea foam or deep green color. This spread of yellow is much more than a single factor yellowface I.

When this mutation is combined with double factor spangle, albino (creamino) or dark eyed clear the yellow coloring is present on the whole body making it look almost like a green series bird, with the strongest yellow areas usually being the face and tail.
