Spare Barrack

#0a073a
Notes

Spare Barrack (#0A073A) is a deep blue 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 (244°, 78%, 13%) 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 yellow. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Spare
adjective

Old English spær, frugal, scant — used as a color modifier since the seventeenth century for hues that read as minimal and unornamented. Spare gray, spare white: very low saturation combined with optical restraint. Sits at the neutral-bucket alongside bare and plain.

Barrack
noun

French baraque, soldier's hut — the deep-cool-gray utilitarian-stone-and-brick soldier-billet architecture of post-Napoleonic European military bases. Barrack color refers to an Aldershot-Garrison-period English barrack-block exterior in November-overcast light: a dark cool-gray with the matte finish of London-stock-brick hand-fired and hand-laid Victorian military barrack-construction.

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.
