Drawn Bluestar

#175586
Notes

Drawn Bluestar (#175586) is a deep azure with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (206°, 71%, 31%) 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 orange. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Drawn
adjective

Old English dragan, to draw — past-participle of draw. As a color modifier, drawn implies a clear-and-line-and-mark quality, the crisp color of Old-Master-and-Modernist hand-drawn studio-and-life-class observational-drawing graphite-and-charcoal lines. Sits at the crisp-and-incised end of the grid, parallel to etched and drafted in usage.

Bluestar
noun

The genus Amsoniabluestar, North American and East Asian native perennials with clusters of pale-blue star-shaped flowers in late spring. A. tabernaemontana and A. hubrichtii are signature pollinator-garden plants. The color refers to a fresh Amsonia flower cluster: a soft, slightly cool pale blue with the matte finish of small five-petaled stars.
