Pristine Hide Lagoon

#3fb6d0
Notes

Pristine Hide Lagoon (#3FB6D0) is a true cyan 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 (191°, 61%, 53%) 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

Pristine
adjective

Latin prīstinus, original / former. As a color modifier, pristine implies a clear-and-untouched quality where the hue carries the original-condition visual register without wear or fade. Sits at the crisp-and-clean end of the grid, parallel to unblemished and spotless in usage.

Hide
modifier

Old English hȳd, skin / hide. As a color modifier, hide implies a tanned-leather-and-skin quality, the visual register of cattle-and-deer-and-pig-hide hand-tanned-and-vegetable-tanned cattle-and-deer-and-pig-skin hand-tanned-leather-hide surfaces under tanned-leather-and-skin tanning-yard light. Sits at the modifier-and-texture end of the grid, parallel to pelt and fur 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.
