Direct Sodalite

#31bdb7
Notes

Direct Sodalite (#31BDB7) 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 (177°, 59%, 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

Direct
adjective

From the Latin directus, straight — used as a color modifier since the eighteenth century for hues that read as straightforward and unambiguous. Direct red, direct green: moderate-to-high saturation combined with optical clarity. Sits at the crisp-bucket center alongside clear and frank.

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.

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.
