Sure Chá

#ad6f2a
Notes

Sure Chá (#AD6F2A) is a true orange 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 (32°, 61%, 42%) 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 azure. 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.

Chá
noun

The Chinese word for tea — used as a color word for the warm brown of brewed tea liquor and the wood of chá-jī (tea tables). The color refers to fresh-brewed Pu-erh tea in a porcelain cup: a soft, slightly cool deep brown with the optical depth of well-fermented tea. Cooler than caramel, 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.
