Pragmatic Marine

#536d87
Notes

Pragmatic Marine (#536D87) is a true azure with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (210°, 24%, 43%) places it in the muted 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

Pragmatic
adjective

Greek pragmatikós, of business / practical — adjectival suffix -ic. As a color modifier, pragmatic implies a clear-and-purpose-fit-and-no-nonsense quality where the hue carries the visual register of straightforward-utilitarian-and-functional decision-making. Sits at the crisp-and-functional end of the grid, parallel to practical and functional in usage.

Marine
noun

From the Latin marinus, of the sea — borrowed via French as both noun and adjective. Marine blue refers to the deep working blue of merchant-ship paint and naval uniforms before navy took over the term in the twentieth century. The color is a saturated, slightly muted deep blue with the matte finish of a shipyard pigment. Cooler than cobalt, warmer than navy, with the maritime weight of a word shared by every Romance language.
