Drained Lunar

#171f67
Notes

Drained Lunar (#171F67) 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 (234°, 63%, 25%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. 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

Drained
adjective

Old English drēahnian, to filter — past-participle of drain. As a color modifier, drained implies a deep-and-emptied-and-pallid quality where the hue's vital warmth has been removed. Sits at the deep-and-cool end of the grid, parallel to deathly with desaturation overtone.

Lunar
noun

Latin luna, moon — adopted into English as the adjective for moon-related phenomena. The lunar color tradition refers to the deep blue-violet of Apollo-program lunar-orbit Earthrise photography (1968–1972) showing the deep blue limb of Earth over the gray Moon surface. Lunar color refers to a Hasselblad Earthrise photo's deep-Earth limb: a saturated, slightly cool deep blue-violet with the optical complexity of Earth-atmosphere Rayleigh scattering against the lunar void.

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.
