Surveyed Polynesia

#28978e
Notes

Surveyed Polynesia (#28978E) 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 (175°, 58%, 37%) 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

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.

Polynesia
noun

The vast triangle of Pacific islands — Hawaii, New Zealand, Easter Island, and the islands between. Polynesia refers to the unifying lagoon-blue-green of Polynesian atolls: a saturated, slightly cool deep blue-green with the optical clarity of warm Pacific lagoon water across thousands of cultural-cousin atolls.
