Spartan Cadet

#394cd4
Notes

Spartan Cadet (#394CD4) is a true blue 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 (233°, 64%, 53%) 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 amber. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Spartan
adjective

Greek Spartiátēs, of Sparta — adjectival suffix referring to the Lacedaemonian warrior city. As a color modifier, spartan implies a saturated-and-disciplined-and-formal quality, the deep-rich color of Spartan-hoplite military-class crimson-and-bronze armor-and-cloak. Sits at the bold-and-formal end of the grid, parallel to austere and stern in tone.

Cadet
noun

A pale gray-blue named for the dress uniform of military cadets — particularly the West Point cadet uniform and the British Royal Military College's traditional grays. The color refers to a cadet-uniform fabric: a soft, slightly muted gray-blue with the matte finish of regulation serge wool. Cooler than slate, warmer than steel, with the institutional weight of pre-officer formal dress.

Display P3 representation

The CSS Color 4 wide-gamut form of this color. Both swatches render the same color on every display — the P3 form only diverges from sRGB when a designer pushes channels outside sRGB's reach.

This color is chromatic enough that authoring it as P3 native (instead of clamping to sRGB) gives a perceptibly more saturated render on wide-gamut displays — modern Macs, iPhones, iPads, and most recent OLED laptops.
