Truthful Tea

#18a99b
Notes

Truthful Tea (#18A99B) is a true teal with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (174°, 75%, 38%) 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

Truthful
adjective

Old English trēowth, truth — adjectival suffix -ful. As a color modifier, truthful implies a clear-and-honest-and-direct quality where the hue carries the visual register of accurate-and-faithful-representation declaration. Sits at the crisp-and-honest end of the grid, parallel to candid and honest in usage.

Tea
noun

The processed leaves of Camellia sinensis, in either its assamica or sinensis variety. The color tea refers to the dried green tea leaves before brewing: a soft, slightly muted gray-green with the matte finish of withered and rolled foliage. Cooler than sage, warmer than matcha, with the ritual weight of a beverage drunk daily by half the world.

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.
