Drawn Patina

#a4d9bc
Notes

Drawn Patina (#A4D9BC) is a soft teal 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 (147°, 41%, 75%) places it in the balanced band at a light lightness. It works as a background wash, large-area fill, or soft illustration tone. Add a darker ink of the same hue when you need type over it. For a confident two-color system, pair it with its complementary magenta. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Drawn
adjective

Old English dragan, to draw — past-participle of draw. As a color modifier, drawn implies a clear-and-line-and-mark quality, the crisp color of Old-Master-and-Modernist hand-drawn studio-and-life-class observational-drawing graphite-and-charcoal lines. Sits at the crisp-and-incised end of the grid, parallel to etched and drafted in usage.

Patina
noun

The thin corrosion layer that develops on copper, bronze, and other metals over time — sometimes copper carbonate (verdigris), sometimes copper sulfate, depending on environment. The color refers to mature exposed-bronze patina on a public statue: a soft, slightly muted blue-green with the powdery finish of mineral oxide. Drabber than verdigris, cooler than celadon, with the slow-time weight of a surface that records its age.
