Drafted Bluegrass

#66c5a6
Notes

Drafted Bluegrass (#66C5A6) is a true teal 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 (160°, 45%, 59%) 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.

Bluegrass
noun

Poa pratensis, Kentucky bluegrass — the cool-season turf grass that dominates lawns of the American Northeast and Midwest. Bluegrass music takes its name from the same plant via Bill Monroe's bluegrass-state Kentucky band. The color refers to a fresh-mown Kentucky bluegrass lawn: a soft, slightly cool blue-green-gray with the matte finish of cropped grass.
