Sanitary Hanada
Sanitary Hanada (#37859D) is a true cyan with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (194°, 48%, 42%) 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
Latin sānitās, health — adjectival suffix -ary. As a color modifier, sanitary implies a clear-and-clean-and-medical quality, the crisp color of Bauhaus-and-Modern clinical-and-hospital interior-architecture white-tile-and-stainless-steel surfaces. Sits at the crisp-and-clean end of the grid, parallel to hygienic and sterile in usage.
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.
