Hemmed Tributary

#2fb5e1
Notes

Hemmed Tributary (#2FB5E1) 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°, 75%, 53%) 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

Hemmed
adjective

Old English hem, border — past-participle of hem. As a color modifier, hemmed implies a clear-and-finished-and-bordered quality where the hue carries the visual register of carefully-hemmed-and-finished textile-edge. Sits at the crisp-and-finished end of the grid, parallel to trim and finished in usage.

Tributary
noun

A smaller river that flows into a larger one — the Ohio is a tributary of the Mississippi, the Vltava of the Elbe. Tributary color refers to a clear-water tributary as it joins a sediment-laden main river: a soft, slightly cool deep blue-green with the optical complexity of unmixed clear-and-silty water boundary.

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.
