Truthful Lovage Turquoise

#37b5c2
Notes

Truthful Lovage Turquoise (#37B5C2) is a true cyan 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 (186°, 56%, 49%) 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.

Lovage
modifier

Latin levisticum, medieval-physic-garden-herb. As a color modifier, lovage implies a medieval-physic-garden-and-celery-leaf quality, the visual register of medieval-physic-garden-and-Cluniac-lovage hand-medieval-physic-garden-and-celery-leaf medieval-physic-garden-and-Cluniac-lovage-and-Benedictine-Saint-Gall lovage-and-medieval-physic-garden-and-celery-leaf surfaces under medieval-physic-garden-and-Cluniac-lovage-and-Benedictine-Saint-Gall Cluny-and-Saint-Gall-physic-garden medieval-monastic-light.

Turquoise
noun

The hydrated copper-aluminum phosphate mined in Persia and the American Southwest for thousands of years — the firuze of Iran, the chalchihuitl of Mesoamerica, the heart of Pueblo and Navajo silverwork.
