Holographic Asagi

#21c16e
Notes

Holographic Asagi (#21C16E) 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 (149°, 71%, 44%) 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

Holographic
adjective

Greek hólos (whole) and graphé (writing) — adjectival suffix -ic. As a color modifier, holographic implies a saturated-and-multi-angle-shifting quality, the bright color of holographic-credit-card and trading-card dichroic-film 3D-image-reflection. Sits at the bright-and-shifting end of the grid, parallel to iridescent and prismatic 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.
