Burning Algae

#63f3d0
Notes

Burning Algae (#63F3D0) is a true teal with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (165°, 86%, 67%) places it in the highly saturated band at a mid lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. 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

Burning
adjective

The progressive participle of burn — used as a color modifier for hues that read as actively luminous, as if combustion is in progress. Burning red, burning orange: the implication is high saturation combined with thermal heat. Sits in the bright-and-warm corner alongside hot and flame. Slightly more active than smoldering.

Algae
noun

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.
