Spotlit Arugula

#aacd3c
Notes

Spotlit Arugula (#AACD3C) 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 (74°, 59%, 52%) 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 indigo. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Spotlit
adjective

English compound spot + lit — past-participle of spotlight. As a color modifier, spotlit implies a saturated-and-narrow-beam-illuminated quality, the bright color of theatrical-stage-and-museum-display directed-spotlight focused-beam illumination. Sits at the bright-and-saturated end of the grid, parallel to sunlit and brilliant in usage.

Arugula
noun

Eruca vesicaria, the Mediterranean mustard-family green — peppery and bitter, eaten as rocket in British English and rucola in Italian. Arugula color refers to fresh wild arugula leaves: a saturated, slightly muted deep yellow-green with the matte finish of small notched leaves.

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.
