Peaceful Inlaid Ocean

#057c8e
Notes

Peaceful Inlaid Ocean (#057C8E) is a deep 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 (188°, 93%, 29%) places it in the highly saturated band at a dark 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

Peaceful
adjective

Latin pāx, peace — adjectival suffix -ful. As a color modifier, peaceful implies a clear-and-restful-and-calm quality where the hue carries the visual register of Quaker-meeting-house still-and-meditative interior atmosphere. Sits at the crisp-and-calm end of the grid, parallel to serene and placid in usage.

Inlaid
modifier

Old French enlaissier, to-set-in. As a color modifier, inlaid implies a hand-set-and-decorative quality, the visual register of Florentine-and-Italian-Renaissance-pietra-dura hand-set-and-decorative inlaid-stone-and-wood-and-mother-of-pearl pietra-dura-and-marquetry surfaces under Florentine-and-Renaissance hand-inlaid pietra-dura-and-marquetry light. Sits at the modifier-and-texture end of the grid, parallel to carved and tooled in usage.

Ocean
noun

The body of saltwater that covers seventy percent of Earth's surface — a single connected mass divided by convention into Atlantic, Pacific, Indian, Southern, and Arctic. The color refers to the average reflectance of mid-depth temperate ocean: a saturated, slightly green-shifted deep blue with the optical depth of a body of water that absorbs all light below the photic zone. Deeper than mediterranean, cooler than peacock.
