Watery Patina

#b5d8cc
Notes

Watery Patina (#B5D8CC) is a soft teal with a pastel character. It reads calm and airy, with enough chroma to feel intentional rather than washed out. Its HSL profile (159°, 31%, 78%) 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

Watery
adjective

Old English wæter, water — adjectival suffix -y. As a color modifier, watery implies a pale-and-diluted-and-translucent quality, the pale color of watercolor-and-Japanese-sumi heavy-water-dilution paint-and-ink-thinned color. Sits at the pale-and-diluted end of the grid, parallel to diluted and thinned 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.
