I also love Eggplant with green! Here is a card I did almost 3 years ago with Elegant Eggplant and Old Olive, still love it, Elegant Olive Wings by fishymom - Cards and Paper Crafts at Splitcoaststampers
My all time favorite SU color is Cameo Coral! I was on a crafting hiatus when it retired, so I missed the opportunity stock up. I have used my last little bits and I miss it dearly! I was all set to dislike Calypso Coral as it was not my beloved Cameo Coral, but I do like it and enjoy working with it. One color that I was never into until I used it for a color challenge was Apricot Appeal. It did not become a super favorite, but I did find myself turning to it every so often. Before using it for the color challenge, I would have given it away to anyone who asked!
