Surveyed Bay

#0487bd
Notes

Surveyed Bay (#0487BD) is a true cyan with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (198°, 96%, 38%) 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 orange. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Surveyed
adjective

Old French surveer, to look upon — past-participle of survey. As a color modifier, surveyed implies a clear-and-measured-and-coordinated quality, the crisp color of Mason-Dixon-Line-and-Royal-Navy-Hydrographic scientific-and-cadastral land-and-sea surveying tradition. Sits at the crisp-and-mapped end of the grid, parallel to mapped and plotted in usage.

Bay
noun

A body of water partially enclosed by land — Chesapeake, Tokyo, Hudson, Naples. The color refers to the average reflectance of a temperate bay on a clear day: a saturated, slightly muted blue with the optical depth of mid-salinity water. Cooler than peacock, warmer than navy, with the geographic specificity of a word that names the largest indentations in every world coastline.

Display P3 representation

The CSS Color 4 wide-gamut form of this color. Both swatches render the same color on every display — the P3 form only diverges from sRGB when a designer pushes channels outside sRGB's reach.

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.
