Drafted Echium

#2fa9b0
Notes

Drafted Echium (#2FA9B0) is a true 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°, 58%, 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

Drafted
adjective

Old English draht, draft — past-participle of draft. As a color modifier, drafted implies a clear-and-line-and-measured quality, the crisp color of Mid-Century-Modern hand-drafted architectural-and-engineering studio-drawing precision-tool-rendered lines. Sits at the crisp-and-incised end of the grid, parallel to drawn and plotted in usage.

Echium
noun

The genus Echium — Mediterranean and Macaronesian biennials with tall deep-blue flower spikes. E. vulgare (viper's bugloss) covers European chalk grasslands; E. wildpretii of Tenerife produces three-meter spires. The color refers to fresh E. vulgare in flower: a saturated, slightly cool deep blue-violet.
