Heartening Catmint

#39b38f
Notes

Heartening Catmint (#39B38F) is a true teal with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (162°, 52%, 46%) 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

Heartening
adjective

Old English heorte (heart) — present-participle of hearten. As a color modifier, heartening implies a clear-and-uplifting-and-encouraging quality where the hue carries the visual register of cheerful-encouraging color-tone. Sits at the crisp-and-cheerful end of the grid, parallel to welcoming and cheerful in usage.

Catmint
noun

The genus Nepeta — particularly N. mussinii (catmint), the cottage-garden perennial with silver-green foliage and lavender-blue flower spikes. The color refers to a fresh catmint clump in May: a soft, slightly cool gray-green with the matte finish of small mint-family leaves. Cooler than santolina.

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.
