NikkiHays!
I'd like to suggest Sunday Gloves for your white one. Mine is white, but almost always shows up as the same color that yours does when I take a picture of it.
Daylily (Hemerocallis 'Sunday Gloves')
As you'll see in the pictures, sometimes it looks white, but it also looks yellow, at least in the pictures.
If you are brave enough to go to the Lily Auction, you are much braver than I am!
