Spotlit Bluegrass

#21ccaa
Notes

Spotlit Bluegrass (#21CCAA) is a true teal with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (168°, 72%, 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 red. 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.

Bluegrass
noun

Poa pratensis, Kentucky bluegrass — the cool-season turf grass that dominates lawns of the American Northeast and Midwest. Bluegrass music takes its name from the same plant via Bill Monroe's bluegrass-state Kentucky band. The color refers to a fresh-mown Kentucky bluegrass lawn: a soft, slightly cool blue-green-gray with the matte finish of cropped grass.

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.
