Spectral Margarita

#b9c02d
Notes

Spectral Margarita (#B9C02D) 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 (63°, 62%, 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.

Etymology

Spectral
adjective

Latin spectrum, appearance — adjectival suffix -al. As a color modifier, spectral implies a saturated-and-rainbow-decomposed-and-pure quality, the bright color of Newton-prism sunlight-decomposed seven-color spectrum band. Sits at the bright-and-pure end of the grid, parallel to prismatic and pure in usage.

Margarita
noun

The Mexican-American cocktail of tequila, lime, and triple sec — invented in the late 1930s on the Mexico–US border and served in a salt-rimmed glass. Margarita color refers specifically to a fresh-poured margarita in a coupe: a soft, slightly cool warm yellow-green with the optical clarity of citrus-and-spirits.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
