Mourning Teak

#643b0f
Notes

Mourning Teak (#643B0F) 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 (31°, 74%, 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

Mourning
adjective

Old English murnan, to grieve — present-participle of mourn, sharing root with Old Norse morna. As a color modifier, mourning implies the deep-and-funereal-and-formal-and-Victorian-mourning-period black-textile quality, the dark cool-formality of widow's-weeds-and-funeral-procession. Sits at the deep-and-funereal end of the grid, parallel to funereal and sepulchral.

Teak
noun

Tectona grandis, the Southeast Asian hardwood prized for its weather-resistance and used in shipbuilding, decking, and the colonial-era furniture of British India. The color refers to a freshly oiled Burmese teak deck: a saturated, slightly warm deep gold-brown with the satin finish of natural-oil-rich hardwood. Warmer than oak, drier than mahogany.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
