Heartening Sward

#aceaa6
Notes

Heartening Sward (#ACEAA6) is a soft green with a pastel character. It reads calm and airy, with enough chroma to feel intentional rather than washed out. Its HSL profile (115°, 62%, 78%) places it in the balanced band at a light lightness. It works as a background wash, large-area fill, or soft illustration tone. Add a darker ink of the same hue when you need type over it. 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

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.

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.
