Plotted Glaucium

#a1b3e4
Notes

Plotted Glaucium (#A1B3E4) is a soft azure 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 (224°, 55%, 76%) 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 amber. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Plotted

Old English plot, small piece of ground — past-participle of plot. As a color modifier, plotted implies a clear-and-coordinate-mapped quality, the crisp color of Cartesian-and-graph-paper coordinate-plotted scientific-and-engineering data-visualization plot-line. Sits at the crisp-and-mapped end of the grid, parallel to mapped and surveyed in usage.

Glaucium
noun

The genus Glauciumhorned poppy, Mediterranean coastal-dune annuals with silver-blue foliage and yellow or orange flowers. The genus name traces to the same Greek glaukos as glauque (gray-blue-green). The color refers to mature Glaucium flavum foliage: a soft, slightly cool deep silver-blue with the matte finish of waxy-cuticled coastal-dune leaf.
