Lapsing Senecio

#376057
Notes

Lapsing Senecio (#376057) is a deep teal 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 (167°, 27%, 30%) 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 red. 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.

Senecio
noun

The genus Senecio — particularly the silver-leaved succulents (S. cineraria, S. mandraliscae) used in Mediterranean and California gardens. The color refers to fresh Senecio cineraria foliage: a soft, slightly cool pale silver-green with the matte velvet finish of dense leaf hair.
