Bleak Quartz

#513e24
Notes

Bleak Quartz (#513E24) is a deep amber 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 (35°, 38%, 23%) 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 azure. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Bleak
adjective

Old Norse bleikr, pale — sharing root with English bleach. As a color modifier, bleak implies a deep-and-cold-and-comfortless quality, the dark gray-pale of Yorkshire-Moors and Hebrides late-winter atmospheric-light. Sits at the deep-and-cool end of the grid, parallel to grim and bitter in atmospheric register.

Quartz
noun

Silicon dioxide — the most abundant single mineral on Earth's continental crust, occurring as everything from beach sand to gem-grade rock crystal. Quartz as a color refers to a polished pale-gray quartz crystal: a soft, very pale slightly cool gray with the high specular shine of a translucent silicate. Cooler than pearl, warmer than mist.
