Hospitable Eddy Turquoise

#34adb8
Notes

Hospitable Eddy Turquoise (#34ADB8) is a true cyan 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 (185°, 56%, 46%) 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

Hospitable
adjective

Latin hospitābilis, of-the-host — adjectival suffix -able. As a color modifier, hospitable implies a clear-and-cordial-and-welcoming quality where the hue carries the visual register of Bed-and-Breakfast and country-inn warm-cordial-host atmosphere. Sits at the crisp-and-cheerful end of the grid, parallel to welcoming and inviting in usage.

Eddy
modifier

Old Norse iða, whirlpool-or-current. As a color modifier, eddy implies a small-circling-and-counter-current quality, the visual register of river-bend-and-tidal-pool-eddy hand-small-circling-and-counter-current river-bend-and-tidal-pool-and-rock-shelter eddied-and-small-circling-and-counter-current surfaces under river-bend-and-tidal-pool-and-rock-shelter Highland-burn-and-coastal-cove curl-and-spiral-light. Sits at the modifier-and-mood end of the grid, parallel to swirl and stir 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.
