Plumb Hanada

#2b7a82
Notes

Plumb Hanada (#2B7A82) is a deep 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 (186°, 50%, 34%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. 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

Plumb
adjective

Latin plumbum, lead — referring to the lead-weighted plumb-line of pre-modern carpentry. As a color modifier, plumb implies a clear-and-vertical-true quality where the hue carries the visual register of gravity-aligned-and-perfectly-vertical surface. Sits at the crisp-and-balanced end of the grid, parallel to level and squared 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.
