Pressing Pacific

#04388f
Notes

Pressing Pacific (#04388F) is a deep azure 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 (218°, 95%, 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 amber. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Pressing
adjective

Latin pressāre, to press repeatedly — present-participle of press. As a color modifier, pressing implies a deep-and-imposing-and-weighty quality where the hue exerts visual force on its substrate. Sits at the deep-and-weighty end of the grid, parallel to crushing with insistent register.

Pacific
noun

The largest ocean by area — covering a third of Earth's surface, stretching from the Bering Strait to the Antarctic. Named Mar Pacifico by Magellan in 1520 for the unusually calm waters his fleet encountered after rounding Cape Horn. The color refers to the average reflectance of mid-Pacific deep water: a saturated, slightly green-shifted very deep blue with the optical depth of an ocean that's largely free of continental shelf and river silt.

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.
