Hyperion is a pale aqua blue with more blue than aqua. It’s opaque in two coats, but the formula was harder to work with; it seemed to pull easily, and I think a ridgefiller might be necessary–you can see the lines of my natural nail and I rarely see those through polish. It’s more opaque and bluer compared to Rescue Beauty Lounge Bikini Bottom. China Glaze Sea Spray is darker. Chanel Riva is bluer.
