Wavelet

Wavelet looks like a sheet of tinted glass laid over a calm blue photo. It's noticeably more muted than Cerulean Skies, so it doesn't feel airy or "hovering," and it stays cooler and cleaner than Summer of '82, which can read brighter and more cyan-forward. Compared with Cuttlefish, Wavelet gives up some depth and lands lighter, with a softer edge rather than that anchored, weighty blue.

I use Wavelet for UI areas that need to look intentional without turning into the main character: secondary panels and section backgrounds in dashboards and finance apps, form field chrome in health platforms, and calm card surfaces in SaaS settings where typography should stay in charge. It's the one you reach for when you want blue to read as blue, but you don't want it to get loud or drift toward teal.

Pair it with darker slate text and a slightly warmer neutral border so it doesn't feel too smooth or a bit washed out next to very cool whites.
