Weighty Hawthorn
Weighty Hawthorn (#309C1F) 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 (112°, 67%, 37%) 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 violet. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Old English wegan, to weigh — adjectival suffix -y. As a color modifier, weighty implies a saturated-and-heavy-and-imposing quality where the hue carries visual mass and gravitational presence. Sits at the bold-and-weighty end of the grid, parallel to substantial and hefty in usage.
Crataegus monogyna, the common European hawthorn — a hedgerow tree whose deep green leaves and red autumn berries are essential to British and Irish countryside. The color refers to mature hawthorn foliage in June: a saturated, slightly cool deep yellow-green with the matte finish of small lobed leaves.
