Grounded Thyme

#18a311
Notes

Grounded Thyme (#18A311) is a true green 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 (117°, 81%, 35%) 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 violet. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Grounded
adjective

Old English grund, bottom / foundation — past-participle of ground. As a color modifier, grounded implies a saturated-and-foundational quality where the hue anchors the surrounding palette through its weighty presence. Sits at the bold-and-balanced end of the grid, parallel to centered and anchored.

Thyme
noun

Thymus vulgaris, the small Mediterranean shrub whose tiny gray-green leaves perfume Provençal cooking and Greek hill country alike. The color refers to fresh thyme sprigs on the cutting board: a soft, slightly muted green with the matte finish of a leaf protected by aromatic oils. Drabber than rosemary, warmer than sage, with the bouquet garni weight of a herb that flavors stocks for hours without falling apart.
