Steady Sodalite

#257683
Notes

Steady Sodalite (#257683) is a deep 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 (188°, 56%, 33%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. 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.

Sodalite
noun

A sodium-aluminum silicate mineral — saturated blue, mined principally in Brazil, Russia, and Greenland. Sodalite is one of the four lazurite-group blue minerals (with lazurite, hauyne, and nosean). The color refers to a polished Brazilian sodalite cabochon: a saturated, slightly cool deep blue with the matte finish of opaque silicate.
