Sparkling Algae
Sparkling Algae (#20C780) 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 (154°, 72%, 45%) 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
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.
A vast collection of photosynthetic eukaryotes — green algae (Chlorophyta), kelps (Phaeophyceae), and dozens of other lineages — that gave rise to all land plants and still produce roughly half of Earth's oxygen. The color refers to a green algal bloom on a still pond: a saturated, slightly muted yellow-green with the matte chlorophyll finish of cellular density. Brighter than moss, cooler than spinach, with the geological weight of a kingdom three billion years old.
