Flashing Asagi

#51e59d
Notes

Flashing Asagi (#51E59D) 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°, 74%, 61%) 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

Flashing
adjective

Old English flasch, flash — present-participle of flash. As a color modifier, flashing implies a saturated-and-rapid-on-off quality, the bright color of emergency-vehicle and photographic-flash light-burst surfaces. Sits at the bright-and-flashing end of the grid, parallel to coruscating and flickering in usage.

Asagi
noun

Asagi-iro (浅葱色) — Japanese for light-onion color — a soft pale blue-green traditional in Heian-period kimono linings and Edo-period samurai inner robes. The color refers to a fresh-dyed asagi silk: a soft, slightly cool pale blue-green with the satin finish of plant-and-mordant silk dye. Cooler than mint, lighter than seafoam.

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.
