Refreshing Flit Turquoise

#28b4c8
Notes

Refreshing Flit Turquoise (#28B4C8) 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 (188°, 67%, 47%) 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

Refreshing
adjective

Old French refreschir, to make fresh again — present-participle of refresh. As a color modifier, refreshing implies a clear-and-cool-and-revitalizing quality, the crisp color of Cornish-coast and Hebridean-island fresh-sea-air-and-cool-water revitalization. Sits at the crisp-and-cool end of the grid, parallel to fresh and bracing in usage.

Flit
modifier

Old Norse flytja, to-move-or-shift. As a color modifier, flit implies a quick-darting-and-light-winged quality, the visual register of swallow-and-warbler-flit hand-quick-darting-and-light-winged swallow-and-warbler-and-darting-finch flitted-and-quick-darting-and-light-winged surfaces under swallow-and-warbler-and-darting-finch summer-eaves-and-hedgerow-and-meadow-edge dappled-flight-light. Sits at the modifier-and-mood end of the grid, parallel to hover and flutter 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.
