Quickening Mauritius

#42fad4
Notes

Quickening Mauritius (#42FAD4) 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 (168°, 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.

Old English cwic, living / lively — present-participle of quicken. As a color modifier, quickening implies a saturated-and-coming-alive-and-active quality where the hue accelerates visual engagement. Sits at the bright-and-active end of the grid, parallel to animated and invigorating in usage.

Mauritius
noun

The Indian Ocean island east of Madagascar — and the saturated turquoise of Mauritian lagoon water at Le Morne and Tamarin Bay. Mauritius color refers to a Mauritian lagoon at midday: a saturated, slightly cool deep blue-green with the optical clarity of warm Indian Ocean water.
