Drafted Rocky

#5b6c8d
Notes

Drafted Rocky (#5B6C8D) is a true azure with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (220°, 22%, 45%) places it in the muted 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 amber. 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.

Rocky
noun

The North American mountain range — and the saturated deep blue of Rocky Mountain alpine lakes (Bear Lake, Sapphire Lake, Lake Louise) at high altitude. Rocky refers to Sapphire Lake in Montana's Glacier National Park: a saturated, slightly cool deep blue with the optical clarity of glacier-fed alpine lake.
