Cleansed Titan Verdigris

#28b3b1
Notes

Cleansed Titan Verdigris (#28B3B1) 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 (179°, 63%, 43%) 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

Cleansed
adjective

Old English clǣnsian, to make clean — past-participle of cleanse. As a color modifier, cleansed implies a clear-and-purified quality where the hue has been stripped of any contaminating tint. Sits at the crisp-and-clear end of the grid, parallel to fresh and pristine in usage.

Titan
modifier

Greek Τιτάν, primeval-Titan-or-Saturn-moon. As a color modifier, titan implies a Saturn-moon-and-methane-haze-and-primeval quality, the visual register of Saturn-moon-Titan-and-Cassini-Huygens hand-Saturn-moon-and-methane-haze-and-primeval Saturn-moon-Titan-and-Cassini-Huygens-and-Kraken-Mare titan-and-Saturn-moon-and-methane-haze surfaces under Saturn-moon-Titan-and-Cassini-Huygens-and-Kraken-Mare orange-haze-and-cryo-volcano-and-methane-lake outer-system-light. Sits at the modifier-and-cosmic end of the grid, parallel to saturn and neptune in usage.

Verdigris
noun

The basic copper carbonate that forms on weathered copper and bronze — the pigment scraped from oxidized metal and used in Renaissance painting before being supplanted by more stable greens. The color refers to a thick verdigris on aged copper roofing or the Statue of Liberty's surface: a soft, slightly muted blue-green with the powdery finish of mineral oxide. Cooler than patina, warmer than seafoam, with the archaeological weight of a mineral made by time.
