Balanced Looped Turquoise

#3bb8c9
Notes

Balanced Looped Turquoise (#3BB8C9) 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 (187°, 57%, 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 red. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Balanced
adjective

The past participle of balance, to weigh evenly. Used as a color modifier since the eighteenth century for hues that read as neither overcommitted nor restrained. Balanced sage, balanced taupe: moderate saturation combined with optical equilibrium. Sits at the crisp-bucket center alongside even.

Looped
modifier

Old French loupe, loop. As a color modifier, looped implies a hand-looped-and-curled quality, the visual register of hand-looped-knit-and-rope hand-looped-and-curled knit-and-rope-and-cord hand-looped-and-curled-loop-and-curl surfaces under hand-looped-and-curled knit-and-rope-and-cord working light. Sits at the modifier-and-texture end of the grid, parallel to coiled and twined 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.
