Neat Night Teal
Neat Night Teal (#18C1B0) 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 (174°, 78%, 43%) places it in the highly saturated band at a mid lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. 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 French net, clean / pure — sharing root with Latin nitidus. As a color modifier, neat implies a clear-and-orderly quality where the hue carries the well-arranged visual register without clutter or excess. Sits at the crisp-and-orderly end of the grid, parallel to trim and tidy in usage.
Old English niht, darkness-and-sleep. As a color modifier, night implies a moonlit-or-star-lit-dark quality, the visual register of clear-sky moonlit-and-star-lit atmospheric Rayleigh-scattered low-light surfaces against deep blue-black night-sky horizon. Sits at the modifier-and-time end of the grid, parallel to eve and yore in usage.
Anas crecca, the small dabbling duck whose male in breeding plumage sports a chestnut head crossed by a glossy green-blue stripe. The color refers to that stripe — the iridescent panel just behind the eye: a saturated, slightly muted blue-green with the optical depth of structural color rather than pigment. Cooler than cypress, warmer than cerulean, with the ornithological specificity of a color named for one feather of one bird.
Closest matches

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.
