Lustrous Chá

#d1b633
Notes

Lustrous Chá (#D1B633) is a true amber 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 (50°, 63%, 51%) 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

Lustrous
adjective

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.

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.
