Plainspoken Nocturne

#6a688a
Notes

Plainspoken Nocturne (#6A688A) 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 (244°, 14%, 47%) places it in the muted 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

Plainspoken
adjective

English compound plain + spoken — past-participle of speak. As a color modifier, plainspoken implies a clear-and-direct-and-straightforward quality where the hue carries the visual register of unembellished-honest declaration. Sits at the crisp-and-honest end of the grid, parallel to candid and direct 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.
