Gaudy Hanada

#1bb3df
Notes

Gaudy Hanada (#1BB3DF) 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 (193°, 78%, 49%) places it in the highly saturated band at a mid 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

Gaudy
adjective

Middle English gaude, trick / showy ornament — adjectival suffix -y. As a color modifier, gaudy implies a saturated-and-cheaply-bright-and-overdone quality, the bright color of carnival-and-fairground novelty-attraction painted-and-lit decoration. Sits at the bright-and-flamboyant end of the grid, parallel to garish and lurid in usage.

Hanada
noun

Hanada-iro (縹色) — a traditional Japanese textile dye color, the saturated medium blue between asagi (light blue-green) and konjō (deep indigo). Used in samurai-period inner robes and Edo-period commoner clothing. The color refers to a hanada-dyed silk: a saturated, slightly cool deep blue with the satin finish of plant-and-mordant dye.

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.
