Smoldering Sward

#3ca637
Notes

Smoldering Sward (#3CA637) is a true green 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 (117°, 50%, 43%) 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

Smoldering
adjective

The progressive participle of smolder, to burn slowly without flame. Used as a color word since the late nineteenth century for the deep reds and oranges of barely-flame coal — the warm saturated darks where the heat is internal rather than emitted. Sits in the bold-and-warm corner, slightly less luminous than burning and slightly less calm than rich.

Sward
noun

A grassy turf — the layer of grass-and-roots covering pasture and lawn. Sward in English landscape vocabulary names the saturated green of well-managed grazing land. The color refers to a freshly mown English country lawn: a saturated, slightly cool yellow-green with the matte finish of cropped grass.
