Smooth Stir Turquoise

#45ddcd
Notes

Smooth Stir Turquoise (#45DDCD) is a true teal with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (174°, 69%, 57%) 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

Smooth
adjective

Old English smōþ, level, polished — used as a color modifier since the seventeenth century for hues that read as continuous without texture or break. Smooth tan, smooth gray: moderate saturation combined with optical evenness. Sits in the crisp-bucket alongside even.

Stir
modifier

Old English styrian, to-move-or-agitate. As a color modifier, stir implies a slow-moved-and-rippled-and-agitated quality, the visual register of cauldron-and-tea-cup-stir hand-slow-moved-and-rippled-and-agitated cauldron-and-tea-cup-and-pot-au-feu stirred-and-slow-moved-and-rippled-and-agitated surfaces under cauldron-and-tea-cup-and-pot-au-feu kitchen-hearth-and-witch's-fire-and-parlor-tea-table simmer-and-eddy-light. Sits at the modifier-and-mood end of the grid, parallel to swirl and eddy 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.
