Hospitable Slush Turquoise

#88fdf8
Notes

Hospitable Slush Turquoise (#88FDF8) is a soft 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 (177°, 97%, 76%) places it in the highly saturated band at a light 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

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.

Slush
modifier

Imitative origin, half-melted-snow. As a color modifier, slush implies a half-melted-snow-and-grey-pavement quality, the visual register of city-pavement-and-thaw-slush hand-half-melted-snow-and-grey-pavement city-pavement-and-thaw-slush-and-Boston-Brooklyn-thaw slush-and-half-melted-snow-and-grey-pavement surfaces under city-pavement-and-thaw-slush-and-Boston-Brooklyn-thaw Boston-and-Brooklyn-and-Edinburgh-thaw urban-thaw-light. Sits at the modifier-and-weather end of the grid, parallel to thaw and flurry 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.
