Lapsing Ebony

#535b4a
Notes

Lapsing Ebony (#535B4A) is a deep lime 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 (88°, 10%, 32%) places it in the muted 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

Lapsing
adjective

Latin lāpsus, fall — present-participle of lapse. As a color modifier, lapsing implies a hushed-and-slipping-and-receding quality where the hue carries the visual register of gradually-slipping-and-falling-from-attention period-correct color. Sits at the hushed-and-fading end of the grid, parallel to fading and waning in usage.

Ebony
noun

The genus Diospyros — particularly D. ebenum of Sri Lanka and D. crassiflora of West Africa — whose dense black heartwood has been carved for ornament since the Egyptian Old Kingdom. The color refers to polished African blackwood: a deep, slightly warm matte black with the satin finish of close-grained hardwood. Warmer than obsidian, drier than pitch, with the carving weight of a wood that sinks in water and sharpens its own tools.
