Flying Fish Blue

Deep sea-blue with violet lift for primary UI
About Flying Fish Blue
Flying Fish Blue looks like a calm action button that's been lightly dipped in sea air. It's a cleaner, brighter blue than the frosty periwinkle feel of Frosted Blueberries, and it doesn't carry that midpoint purple warmth of Blurple. Compared to the flat authority of Blue Screen of Death, this one has more lift and a softer temperature shift toward purple without going smoky.
I use Flying Fish Blue for UI moments that need to read clearly but stay friendly: primary CTAs, hover and focus states, and key chart series in SaaS dashboards and e-commerce admin panels. It's also great for onboarding steps where you want urgency without sounding like an error. This shade stays crisp in dense tables, but it won't feel as heavy or absolute as that "serious blue" look.
Quirk: if you stack it next to very saturated purples, it can start to feel a little too cool. Pair with neutrals that are slightly warm so it keeps its "light-in-the-water" edge.
