I only have Champagne Elegance, not sure I would consider it buff/yellow, more very, very light pink with dark orange/peach falls. It is pretty, but not one of my favorites. Mainly because seems when I get fall blooms, I probably won't get spring blooms. Just not the best bloomer in my garden. I have New Dawning that I think is a pretty, soft yellow. I also have Sky Hooks, it is yellow/white combo with blue horns, I have it planted beside Blue Reflections & think they look really nice together.
