Fresh Domus Turquoise

#55d9cc
Notes

Fresh Domus Turquoise (#55D9CC) is a true teal with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (174°, 63%, 59%) places it in the balanced band at a mid lightness. It works across type, buttons, and borders, saturated enough to feel deliberate but balanced enough to not fight the rest of the palette. 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

Fresh
adjective

Old English fersc, unsalted / not stale — sharing root with German frisch. As a color modifier, fresh implies a clear-and-newly-applied quality where the hue carries the just-emerged visual register. Sits at the crisp-and-clean end of the grid, parallel to crisp and new in usage.

Domus
modifier

Latin domus, house-or-home. As a color modifier, domus implies a Latin-house-and-Roman-domus-and-atrium quality, the visual register of Pompeian-domus-and-Roman-atrium hand-Latin-house-and-Roman-domus-and-atrium Pompeian-domus-and-Roman-atrium-and-impluvium domus-and-Latin-house surfaces under Pompeian-domus-and-Roman-atrium-and-impluvium Pompeian-and-Herculaneum-domus Roman-villa-light. Sits at the modifier-and-Latin end of the grid, parallel to arbor and via in usage.

Turquoise
noun

The hydrated copper-aluminum phosphate mined in Persia and the American Southwest for thousands of years — the firuze of Iran, the chalchihuitl of Mesoamerica, the heart of Pueblo and Navajo silverwork. The color refers to a fine Sleeping Beauty turquoise from Arizona: a saturated, slightly green-shifted blue with the slight matrix of host-rock veining. Brighter than persian, lighter than cerulean.
