Sparkling Roller

#21d290
Notes

Sparkling Roller (#21D290) 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 (158°, 73%, 48%) 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

Sparkling
adjective

Old English spearca, spark — present-participle of sparkle. As a color modifier, sparkling implies a saturated-and-multi-point-reflective-and-effervescent quality, the bright color of Champagne-and-Prosecco effervescent-wine carbonation-bubble-light reflection. Sits at the bright-and-reflective end of the grid, parallel to glittering and fizzy in usage.

Roller
noun

The family Coraciidae — Old World rollers whose acrobatic flight gives the family its name. Coracias caudatus (lilac-breasted roller) of southern Africa displays saturated turquoise wing covers. The color refers to a male lilac-breasted roller's wing: a saturated, slightly cool deep turquoise.
