Dependable Hanada

#428ca0
Notes

Dependable Hanada (#428CA0) 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 (193°, 42%, 44%) 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

Dependable
adjective

Latin dē-pendere, to hang from — adjectival suffix -able. As a color modifier, dependable implies a clear-and-trustworthy-and-consistent quality where the hue carries the visual register of consistently-performing-and-counted-on design-element. Sits at the crisp-and-honest end of the grid, parallel to reliable and trustworthy 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.
