Plotted Vega Lagoon

#1eb7d8
Notes

Plotted Vega Lagoon (#1EB7D8) 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 (191°, 76%, 48%) places it in the highly saturated band at a mid lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. 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.

Vega
modifier

Arabic al-nasr-al-wāqi', the-falling-eagle. As a color modifier, vega implies a brilliant-blue-white-and-summer-zenith quality, the visual register of Lyra-constellation-and-northern-summer-Vega hand-brilliant-blue-white-and-summer-zenith Lyra-constellation-and-northern-summer-and-Bortle-1-sky vega-and-brilliant-blue-white-and-summer-zenith surfaces under Lyra-constellation-and-northern-summer-and-Bortle-1-sky July-and-August-northern-zenith deep-sky-light. Sits at the modifier-and-cosmic end of the grid, parallel to deneb and altair in usage.

Lagoon
noun

A shallow body of saltwater partially or fully enclosed by a barrier — coral atoll lagoons in the Pacific, Venice's Laguna Veneta, the Florida Keys' backcountry. The color refers to the average reflectance of a calm tropical lagoon at midday: a saturated, slightly muted blue-green with the optical clarity of shallow water over white sand. Brighter than reef, cooler than aquamarine, with the postcard weight of a Pacific atoll seen from above.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
