Charged Senecio

#40fac9
Notes

Charged Senecio (#40FAC9) is a true teal with a neon character. It sits at the high-saturation edge of its family. Use it sparingly, as signage, accent, or highlight against darker surfaces. Its HSL profile (164°, 95%, 62%) places it in the highly saturated band at a mid lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. 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

Charged
adjective

Old French chargier, to load — past-participle of charge, sharing root with cargo. As a color modifier, charged implies a saturated-and-electrically-loaded quality where the hue carries visual potential-energy. Sits at the bright-and-active end of the grid, parallel to electrified and energetic 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.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
