Blended aquadisiac and freshwater go FABULOUS together, it makes a brighter tuqouisy color and will make your eyes POP. also try blending tilt and moons reflection.
I love using blues with browns. My favorite combos are Sable on the lid, Electro Sky blended into the center; or Behold on the lid with Meadowland blended into the center.
I have Freshwater and Tilt. I don't reach for Freshwater often, but it is a beautiful color and makes a very pretty liner. Yesterday, I wore Brill (dc but you might still be able to find it!) on the inner lid, Tilt on the middle lid, and Steel Blue on the outer v with brown liner. It looked so pretty and I got tons of compliments on it!
i personally love contrast...but i wear a lot of blue shadows i like using electric eel over graphito paint to mak e a deeper blue then using belle azure in the crease and my lower lash line...
