Frank Chá

#89724a
Notes

Frank Chá (#89724A) is a true amber with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (38°, 30%, 41%) 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

Frank
adjective

From the Old French franc, free, sincere — used as a color modifier since the seventeenth century for hues that read as direct and unhedged. Frank red, frank brown: moderate-to-high saturation combined with optical directness. Sits at the crisp-bucket alongside direct and honest.

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.
