Earnest Reseda
Earnest Reseda (#668819) is a deep lime 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 (78°, 69%, 32%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. For a confident two-color system, pair it with its complementary indigo. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Old English eornost, seriousness, zeal. Used as a color modifier since the nineteenth century for hues that read as committed but unshowy — the working blues of denim, the deep greens of Quaker meetinghouses. Sits in the bold-and-quiet corner of the grid, slightly less luminous than resolute and slightly less institutional than imperial.
Reseda luteola, dyer's weed — a Mediterranean herb cultivated for the yellow dye extracted from its leaves and stalks since Roman times. Reseda as a color refers to a desaturated yellow-green: the soft, slightly muted shade of dried mignonette stems before extraction, or the pale ground of a Regency-era wallpaper. Cooler than sage, warmer than celadon, with the historical weight of an industrial-textile pigment.
