Smooth Yùhuáng
Smooth Yùhuáng (#D9E586) is a soft yellow 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 (68°, 65%, 71%) places it in the balanced band at a light lightness. It works as a background wash, large-area fill, or soft illustration tone. Add a darker ink of the same hue when you need type over it. For a confident two-color system, pair it with its complementary blue. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Old English smōþ, level, polished — used as a color modifier since the seventeenth century for hues that read as continuous without texture or break. Smooth tan, smooth gray: moderate saturation combined with optical evenness. Sits in the crisp-bucket alongside even.
Literally jade-yellow in Chinese — a soft, slightly cool pale yellow used in ceremonial hetian nephrite jade and in the silks of Qing-dynasty consort robes. The color refers to a polished pale-yellow nephrite cabochon: a soft, slightly cool pale yellow with the satin finish of fine jade.
