Tidy Hanada

#0a8790
Notes

Tidy Hanada (#0A8790) is a deep cyan with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (184°, 87%, 30%) places it in the highly saturated band at a dark 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

Tidy
adjective

Old English tidig, timely — drifted in modern English to mean neat, orderly. Used as a color modifier for hues that read as composed and unfussy. Tidy beige, tidy gray: moderate saturation combined with optical neatness. Sits at the crisp-bucket alongside plain and modest.

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.
