Infused Nocturne

#2f3197
Notes

Infused Nocturne (#2F3197) is a true blue 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 (239°, 53%, 39%) 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 yellow. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Infused
adjective

Latin infundere, to pour into — past-participle of infuse. As a color modifier, infused implies a deep-pigment-and-warmth where the hue has been filled from within with the source dye. Sits at the deep-and-saturated end of the grid, parallel to suffused and steeped in usage.

Nocturne
noun

French nocturne, night-piece — adopted into music by John Field (Irish, 1812) and Frédéric Chopin (Polish, 1827–46) for piano character pieces evoking nighttime, and into painting by James McNeill Whistler for a series of deep-blue-violet Thames-river twilights. Nocturne color refers to a Whistler Nocturne in Black and Gold foreground tonality: a saturated, slightly cool deep blue-violet with the soft finish of thinned oil over warm gesso.

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.
