Drained Convolvulus

#172351
Notes

Drained Convolvulus (#172351) is a deep blue 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 (228°, 56%, 20%) 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 amber. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Drained
adjective

Old English drēahnian, to filter — past-participle of drain. As a color modifier, drained implies a deep-and-emptied-and-pallid quality where the hue's vital warmth has been removed. Sits at the deep-and-cool end of the grid, parallel to deathly with desaturation overtone.

Convolvulus
noun

The genus Convolvulusbindweed — including the saturated blue-flowered Mediterranean C. sabatius (ground morning-glory) of southern European rock gardens. The color refers to a fresh C. sabatius at peak summer bloom: a saturated, slightly cool deep blue with the satin finish of trumpet-shaped flower.
