Sorry to hear you've got a head cold- my DH is laid up with one too at the moment. Hope it clears up soon! I would vote for Old Olive as one of the most versatile SU! colours of all time, seriously, especially if you're looking for a green that's softer but not too pale. Old Olive is a lovely, nature-theme kind of green, and goes with pretty much anything. I've made great use of the ink and cardstock for both masculine and feminine cards.
Get well soon!
