Organized Cascade

#3176a1
Notes

Organized Cascade (#3176A1) is a true azure with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (203°, 53%, 41%) 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 orange. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Organized
adjective

Greek órganon, instrument / tool — past-participle of organize. As a color modifier, organized implies a clear-and-coordinated-and-systematic quality where the hue carries the visual register of well-coordinated-and-classified arrangement. Sits at the crisp-and-orderly end of the grid, parallel to orderly and methodical in usage.

Cascade
noun

A waterfall of moderate size — particularly the Cascade Range of waterfalls along the Pacific Northwest's Columbia River Gorge. Cascade color refers to the white-and-blue of falling water at Multnomah Falls: a soft, slightly cool pale blue-white with the optical complexity of mist-and-water in motion.

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.
