Plainspoken Bottle

#57c8b2
Notes

Plainspoken Bottle (#57C8B2) is a true 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 (168°, 51%, 56%) 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

Plainspoken
adjective

English compound plain + spoken — past-participle of speak. As a color modifier, plainspoken implies a clear-and-direct-and-straightforward quality where the hue carries the visual register of unembellished-honest declaration. Sits at the crisp-and-honest end of the grid, parallel to candid and direct in usage.

Bottle
noun

The traditional dark green of European wine and beer bottles — produced by adding iron oxide to the glass batch to filter UV that would damage the contents. The color refers to a Riesling or Burgundy bottle held against the light: a deep, slightly blue-shifted green with the optical translucency of glass. Darker than spruce, cooler than forest, with the cellar weight of a color that's been protecting wine since the seventeenth century.
