I noticed that all the blooms here are a solid lemon. Does it ever display the bronze coral overlay?
Bob Carr described it as "Heavily ruffled and sculpted. Yellow base color overlaid with an orange-coral blush accented by a ruffled yellow-gold edge. Small olive green heart."
here are more images on DG, scroll down to see them all. Even the most yellow one shows a bit of coral blush and sculpting.
