Fresh Freshet

#0d636c
Notes

Fresh Freshet (#0D636C) is a deep cyan with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (186°, 79%, 24%) places it in the highly saturated band at a dark lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. For a confident two-color system, pair it with its complementary red. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Fresh
adjective

Old English fersc, unsalted / not stale — sharing root with German frisch. As a color modifier, fresh implies a clear-and-newly-applied quality where the hue carries the just-emerged visual register. Sits at the crisp-and-clean end of the grid, parallel to crisp and new in usage.

Freshet
noun

A sudden flood of fresh water — particularly the spring runoff of melting mountain snow into rivers. Freshet color refers to a freshet-swollen mountain river in late April: a soft, slightly cool deep blue-white with the optical complexity of snowmelt-suspended sediment.
