Truthful Fenugreek

#66f8e5
Notes

Truthful Fenugreek (#66F8E5) 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°, 91%, 69%) 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

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.

Fenugreek
noun

Trigonella foenum-graecum, the Mediterranean and South Asian legume whose seeds are essential to Indian and Ethiopian cooking. The color refers to fresh fenugreek leaves (called methi in Hindi): a soft, slightly cool deep yellow-green-blue with the matte finish of pinnate trifoliate leaf.
