Tucked Heron

#1f6e72
Notes

Tucked Heron (#1F6E72) is a deep cyan with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (183°, 57%, 28%) 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

Tucked
adjective

Old English tūcian, to torment / pull — past-participle of tuck. As a color modifier, tucked implies a clear-and-fitted-and-arranged quality where the hue carries the visual register of carefully-tucked-and-neatly-fitted shirt-into-trouser dress-attire. Sits at the crisp-and-finished end of the grid, parallel to trim and pressed in usage.

Heron
noun

The family Ardeidae — particularly Ardea cinerea (gray heron) of European wetlands and Ardea herodias (great blue heron) of North America, whose plumage is dominated by saturated blue-gray. The color refers to a great blue heron in flight: a soft, slightly cool deep blue-gray with the matte finish of large wading-bird plumage.
