Healthful Burlap

#664013
Notes

Healthful Burlap (#664013) is a deep orange with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (33°, 69%, 24%) 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

Healthful
adjective

Old English hǣlth, health — adjectival suffix -ful. As a color modifier, healthful implies a clear-and-vital-and-wholesome quality where the hue carries the visual register of fresh-air-and-sunlight outdoor health-promoting environment. Sits at the crisp-and-wholesome end of the grid, parallel to salubrious and wholesome in usage.

Burlap
noun

A coarse fabric woven from jute or hemp fiber — used historically for sacking, packing, and rough farm-clothing. The color refers to undyed natural burlap: a soft, slightly muted warm tan with the textured matte finish of bast-fiber weave. Drier than hemp, warmer than canvas.
