Fiery Echeveria

#21c374
Notes

Fiery Echeveria (#21C374) 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°, 71%, 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

Fiery
adjective

Old English fȳr, fire — adjectival suffix -y. As a color modifier, fiery implies a saturated-and-bright-flaming quality, the bright color of autumn-foliage fall-color and forge-furnace hot-iron emission. Sits at the bright-and-warm end of the grid, parallel to flaming and blazing in usage.

Echeveria
noun

The genus Echeveria — Mexican rosette-forming succulents named for the eighteenth-century botanical illustrator Atanasio Echeverría y Godoy. Cultivated globally as ornamental plants for their geometric blue-green form. The color refers to a fresh Echeveria elegans rosette: a soft, slightly cool silver-green-blue with the matte velvet finish of waxy succulent leaves.

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.
