Sure Carnation

#903826
Notes

Sure Carnation (#903826) is a true red with a warm character. It leans warm, pulling light toward red, orange, and yellow. Naturally inviting, it suits editorial and hospitality contexts. Its HSL profile (10°, 58%, 36%) places it in the balanced band at a mid lightness. It works across type, buttons, and borders, saturated enough to feel deliberate but balanced enough to not fight the rest of the palette. For a confident two-color system, pair it with its complementary cyan. 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.

Carnation
noun

Dianthus caryophyllus, the cultivated flower of European bouquets and corsages — bred over centuries from the wild Dianthus. The color refers to a deep red carnation in a florist's display: a saturated, slightly cool deep red with the satin finish of fringed petal edges. Deeper than coral, lighter than burgundy.
