Drafted Mariner

#54dde0
Notes

Drafted Mariner (#54DDE0) 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 (181°, 69%, 60%) 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 red. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Drafted
adjective

Old English draht, draft — past-participle of draft. As a color modifier, drafted implies a clear-and-line-and-measured quality, the crisp color of Mid-Century-Modern hand-drafted architectural-and-engineering studio-drawing precision-tool-rendered lines. Sits at the crisp-and-incised end of the grid, parallel to drawn and plotted in usage.

Mariner
noun

One who sails the sea — from the Latin mare. As a color name, mariner refers to the deep navy-and-cyan of traditional naval and merchant-marine uniforms: a saturated, slightly muted blue with the matte finish of dyed wool. Cooler than navy, warmer than ocean, with the maritime-uniform association of a word that always implies a working boat rather than a recreational one.

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.
