Inscribed Lesbos

#1ab9b4
Notes

Inscribed Lesbos (#1AB9B4) is a true cyan with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (178°, 75%, 41%) 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 red. For something softer, pull in its analogous neighbors on either side of the wheel.

Sits at the crisp-and-incised end of the grid, parallel to etched and engraved in usage.

Lesbos
noun
