Stormy Surkh

#6d2431
Notes

Stormy Surkh (#6D2431) is a deep red 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 (349°, 50%, 28%) 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 teal. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Stormy
adjective

Old English storm, storm — adjectival suffix -y. As a color modifier, stormy implies a deep-and-turbulent-and-cool-shifted quality, the dark cool-gray of Force-9-gale atmospheric-turbulence sky. Sits at the deep-and-turbulent end of the grid, parallel to thunderous and tempestuous in atmospheric register.

Surkh
noun

The Persian word for red in its most saturated, formal sense — used in Iranian poetry and miniature painting for the ribbons of court banners, the robes of warriors, and the high-saturation reds of Safavid tile. The color refers to a surkh-dyed Persian carpet: a saturated, slightly cool deep red with the matte finish of plant-dye-on-wool. Deeper than crimson, warmer than burgundy.
