Inflamed Bluegrass

#28d783
Notes

Inflamed Bluegrass (#28D783) 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 (151°, 69%, 50%) 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 magenta. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Inflamed
adjective

Latin inflammātus, set on fire — past-participle of inflame. As a color modifier, inflamed implies a saturated-and-irritated-hot quality, the bright color of sun-burnt-skin and autumn-leaf high-anthocyanin pigmentation. Sits at the bright-and-warm end of the grid, parallel to fiery and flaming 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.

Display P3 representation

The CSS Color 4 wide-gamut form of this color. Both swatches render the same color on every display — the P3 form only diverges from sRGB when a designer pushes channels outside sRGB's reach.

This color is chromatic enough that authoring it as P3 native (instead of clamping to sRGB) gives a perceptibly more saturated render on wide-gamut displays — modern Macs, iPhones, iPads, and most recent OLED laptops.
