Tidy Slush Turquoise

#30a7d5
Notes

Tidy Slush Turquoise (#30A7D5) is a true cyan with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (197°, 66%, 51%) 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 orange. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Tidy
adjective

Old English tidig, timely — drifted in modern English to mean neat, orderly. Used as a color modifier for hues that read as composed and unfussy. Tidy beige, tidy gray: moderate saturation combined with optical neatness. Sits at the crisp-bucket alongside plain and modest.

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.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
