Etched Bondi

#1c70ab
Notes

Etched Bondi (#1C70AB) is a true azure 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 (205°, 72%, 39%) 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 orange. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Etched
adjective

German ätzen, to etch — past-participle of etch. As a color modifier, etched implies a clear-and-precisely-incised quality, the crisp color of Rembrandt-and-Dürer hand-pulled etching-print fine-line incised-image. Sits at the crisp-and-incised end of the grid, parallel to engraved and inscribed in usage.

Bondi
noun

Bondi Beach, the kilometer of golden sand and surf in eastern Sydney — Australian for water breaking over rocks, from the Aboriginal Dharug word boondi. The color refers to mid-depth Bondi water on a sunny morning: a saturated, slightly green-shifted blue with the optical clarity of South Pacific water hitting a sandstone shoreline. Brighter than aegean, cooler than caribbean, with the surf-culture association of a beach featured in a million postcards.

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.
