Inscribed Tributary
Inscribed Tributary (#79E5DF) 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°, 68%, 69%) 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
Latin īnscrībere, to write upon — past-participle of inscribe. As a color modifier, inscribed implies a clear-and-text-or-pattern-cut quality, the crisp color of Roman-Imperial-period monumental-stone inscription-and-monumental-text incised-relief. Sits at the crisp-and-incised end of the grid, parallel to etched and engraved in usage.
A smaller river that flows into a larger one — the Ohio is a tributary of the Mississippi, the Vltava of the Elbe. Tributary color refers to a clear-water tributary as it joins a sediment-laden main river: a soft, slightly cool deep blue-green with the optical complexity of unmixed clear-and-silty water boundary.
