Steady Murk Turquoise

#34b5c3
Notes

Steady Murk Turquoise (#34B5C3) 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 (186°, 58%, 48%) 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

Steady
adjective

Old English stede, place, position — drifted to mean firm and unmoving. Used as a color modifier since the seventeenth century for hues that read as reliable rather than dramatic. Steady gray, steady green: moderate saturation combined with optical calmness. Sits in the crisp-bucket center alongside settled.

Murk
modifier

Old Norse myrkr, darkness-or-obscurity. As a color modifier, murk implies a clouded-and-dim-and-obscured quality, the visual register of fen-and-bog-and-tarn-murk hand-clouded-and-dim-and-obscured fen-and-bog-and-tarn-and-marsh murky-and-clouded-and-dim-and-obscured surfaces under fen-and-bog-and-tarn-and-marsh peat-stained-and-clouded-and-dim swamp-and-fen-light. Sits at the modifier-and-mood end of the grid, parallel to gloom and pall 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.
