Stark Sappanwood

#642730
Notes

Stark Sappanwood (#642730) 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 (351°, 44%, 27%) 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

Stark
adjective

Old English stearc, stiff / strong — sharing root with German stark and Dutch sterk. As a color modifier, stark implies a deep-and-uncompromising contrast where the hue stands without modulation against its substrate. Sits at the deep-and-formal end of the grid, parallel to severe with sharper visual register.

Sappanwood
noun

Caesalpinia sappan, the Asian counterpart to brazilwood — used as a red dye source in Indian, Indonesian, and Japanese textile tradition. The color refers to sappanwood-dyed cotton: a saturated, slightly cool deep red with the warm tone of brazilein pigment. The Asian cousin of brazilwood.
