Open Mauritius

#a6ece1
Notes

Open Mauritius (#A6ECE1) is a soft teal with a pastel character. It reads calm and airy, with enough chroma to feel intentional rather than washed out. Its HSL profile (171°, 65%, 79%) places it in the balanced band at a light lightness. It works as a background wash, large-area fill, or soft illustration tone. Add a darker ink of the same hue when you need type over it. 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

Open
adjective

Old English open, unobstructed — used as a color modifier since the eighteenth century for hues that read as airy or uncrowded. Open blue, open green: moderate saturation combined with optical spaciousness, the slight visual breath of a hue that doesn't crowd the surface it covers. Sits at the crisp-bucket center alongside clear.

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.
