Lustrous Yunnan
Lustrous Yunnan (#D3D161) is a true 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 (59°, 56%, 60%) 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 blue. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
From the Latin lustrare, to illuminate — used as a color word since the seventeenth century for hues with the slight specular shine of polished metal or silk. Lustrous green, lustrous gold: the implication is moderate-to-high saturation combined with surface reflectivity. Sits at the bright-and-glossy corner alongside gleaming.
The southwestern Chinese province — and the deep yellow of Yunnan Pu-erh tea liquor and the yellow stripe in the jīnhuáng glaze of Tang-dynasty Yunnan ceramics. Yunnan refers to a fresh-brewed Yunnan Pu-erh in a porcelain cup: a saturated, slightly red-shifted gold-yellow with the optical depth of fermented-tea liquor.
