Spotlit Mayonnaise

#b3c01f
Notes

Spotlit Mayonnaise (#B3C01F) is a true yellow with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (65°, 72%, 44%) 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

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.

Mayonnaise
noun

The egg-yolk-and-oil emulsion essential to French sauces (aïoli, rémoulade), American sandwiches, and Japanese Kewpie cuisine. The color refers to fresh-whisked mayonnaise as it sits in a glass jar, slightly mounded from the spoon: a soft, slightly warm pale yellow with the satin finish of high-fat emulsion. Lighter than yolk, warmer than buttermilk.

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.
