Pellucid Freshet

#3fadd7
Notes

Pellucid Freshet (#3FADD7) is a true cyan with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (197°, 66%, 55%) places it in the balanced band at a mid lightness. It works across type, buttons, and borders, saturated enough to feel deliberate but balanced enough to not fight the rest of the palette. For a confident two-color system, pair it with its complementary orange. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Pellucid
adjective

Latin pellūcidus, transparent — derived from per-lūcēre (to shine through). As a color modifier, pellucid implies a clear-and-translucent quality where the hue reads with optical clarity and minimal turbidity. Sits at the crisp-and-clear end of the grid, parallel to lucid and translucent 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.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
