Spotless Lesbos
Spotless Lesbos (#4FDFDD) 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 (179°, 69%, 59%) 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.
Etymology
Old English spott (spot) plus suffix -less. As a color modifier, spotless implies a clear-and-unmarked quality where the hue carries no contaminating speck or stain. Sits at the crisp-and-clean end of the grid, parallel to pristine and unblemished in usage.
The Greek island in the eastern Aegean — and the saturated deep blue of Lesbos's Petrified Forest coastline and Sigri harbor. Lesbos color refers to the harbor water at sunset: a saturated, slightly cool deep blue with the optical depth of warm Aegean coastal water.

Accessibility
How this color appears to viewers with the four major color-vision-deficiency types. Computed via the Machado (2009) physiologically-based model. If a tile matches the original, the color reads the same to that viewer.
The color used as foreground text against pure white and pure black, with the contrast ratio and WCAG 2.1 grade. Aim for AA (4.5:1) for body text and AA Large (3:1) for 18 pt+ headlines; AAA (7:1) is the gold standard for long-form reading surfaces.
Wide gamut
The CSS Color 4 wide-gamut form of this color. Both swatches render the same color on every display — the P3 form only diverges from sRGB when a designer pushes channels outside sRGB's reach.
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.
