Plotted Borage

#42d8d2
Notes

Plotted Borage (#42D8D2) is a true cyan with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (178°, 66%, 55%) 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

Plotted
adjective

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.

Borage
noun

Borago officinalis, the Mediterranean kitchen herb whose star-shaped blue flowers are edible (used in Pimm's Cup cocktails) and whose leaves taste of cucumber. The color refers to a fresh borage flower at peak bloom: a saturated, slightly cool deep blue with the matte finish of star-shaped Boraginaceae flower.
