Stamped Surf

#3fb2d9
Notes

Stamped Surf (#3FB2D9) 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 (195°, 67%, 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

Stamped
adjective

Old English stempan, to stamp — past-participle of stamp. As a color modifier, stamped implies a clear-and-impressed-and-repeating quality, the crisp color of William-Morris-and-Liberty-of-London block-printed-textile carefully-impressed pattern. Sits at the crisp-and-printed end of the grid, parallel to printed and engraved in usage.

Surf
noun

The white water produced where waves break — bubbles of compressed air carried in shallow water and dispersing as the wave reforms. The color refers to surf retreating across wet sand: a soft, very pale blue-green with the optical brightness of bubble dispersion. Lighter than seafoam, cooler than frost, with the kinetic weight of a color that's never still — every photograph of surf is already obsolete.

Display P3 representation

The CSS Color 4 wide-gamut form of this color. Both swatches render the same color on every display — the P3 form only diverges from sRGB when a designer pushes channels outside sRGB's reach.

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.
