Sure Henna

#7c2f3a
Notes

Sure Henna (#7C2F3A) 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°, 45%, 34%) 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

Sure
adjective

Old French seur, certain — used as a color modifier since the medieval period for hues that read as confident and stable. Sure red, sure blue: moderate saturation combined with optical commitment. Sits at the crisp-bucket center alongside steady and true.

Henna
noun

Lawsonia inermis, the small flowering shrub of North Africa and South Asia whose dried leaves yield a red-brown dye used since the Bronze Age for skin, hair, and textile. The color refers to fresh henna paste applied to skin, where it oxidizes to a deep brick-red over forty-eight hours. Earthier than rose, more orange than maroon, with the slow-developed quality particular to plant-based dye.
