Lucid Libra Teal

#1dac9a
Notes

Lucid Libra Teal (#1DAC9A) is a true teal with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (172°, 71%, 39%) 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

Lucid
adjective

Latin lūcidus, clear / bright — derived from lūx (light). As a color modifier, lucid implies a clear-and-readable quality where the hue is unambiguous and free of optical clutter. Sits at the crisp-and-clear end of the grid, parallel to pellucid and plain in usage.

Libra
modifier

Latin libra, scales-of-the-zodiac. As a color modifier, libra implies a scales-and-air-sign-and-Venus-ruled-cardinal-air quality, the visual register of Roman-Libra-and-scales-of-justice hand-scales-and-air-sign-and-Venus-ruled-cardinal-air Roman-Libra-and-scales-of-justice-and-Themis-Astraea libra-and-scales-and-air-sign surfaces under Roman-Libra-and-scales-of-justice-and-Themis-Astraea autumn-equinox-and-September-and-October cardinal-air-sign-light. Sits at the modifier-and-zodiac end of the grid, parallel to virgo and scorpio in usage.

Teal
noun

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.

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.
