Sullen Burtuqāl

#3e1f0e
Notes

Sullen Burtuqāl (#3E1F0E) 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 (21°, 63%, 15%) 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

Sullen
adjective

Old French solain, solitary via Anglo-French solein. As a color modifier, sullen implies a deep-and-cool-and-withholding quality, the dark cool-gray of Norwegian-fjord mid-winter atmospheric-overcast and saturated-saltwater-cliff in late-November light. Sits at the deep-and-cool end of the grid, parallel to gloomy and saturnine in atmospheric tone.

Burtuqāl
noun

The Arabic word for orange — borrowed from Burtuqāl (Portugal), which introduced sweet oranges (Citrus sinensis) to the Mediterranean from East Asian sources in the sixteenth century. The color refers to fresh Arabic-grown sweet oranges: a saturated, slightly cool orange with the satin finish of citrus rind. The Arab-world's name for a fruit named for the country that brought it.
