Ostentatious Indochina

#adbf2a
Notes

Ostentatious Indochina (#ADBF2A) 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 (67°, 64%, 46%) 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.

Sits at the bright-and-flamboyant end of the grid, parallel to flamboyant and showy in usage.

Indochina
noun

The historical name for mainland Southeast Asia — Vietnam, Laos, Cambodia. Indochina as a color refers to the warm yellow of Cambodian and Vietnamese rice paddies in late autumn: a saturated, slightly red-shifted gold-yellow with the matte finish of ripening grain across an entire landscape.
