Refined Submarine

#211001
Notes

Refined Submarine (#211001) is a deep orange 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 (28°, 94%, 7%) 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 azure. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Refined
adjective

Latin re- plus fīnis — past-participle of refine. As a color modifier, refined implies a neutral-and-elegantly-stripped-down-and-cultivated quality, the neutral color of Edwardian-and-Belle-Époque refined-and-stripped-of-excess elegant-and-cultivated interior-decoration-and-dress-attire coordinated-color tone. Sits at the neutral-and-cultivated end of the grid, parallel to cultured and polished in usage.

Submarine
noun

The military-naval underwater vessel — and the dark gray paint applied to the surface portions of submarine hulls to minimize visual signature against the gray of an ocean horizon. The color refers to a NATO submarine's exposed sail: a soft, slightly muted dark blue-gray with the matte finish of marine anti-corrosion enamel. Cooler than gunmetal, warmer than midnight.
