Fresh Starlight

#543e81
Notes

Fresh Starlight (#543E81) is a true indigo 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 (260°, 35%, 37%) 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 lime. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Fresh
adjective

Old English fersc, unsalted / not stale — sharing root with German frisch. As a color modifier, fresh implies a clear-and-newly-applied quality where the hue carries the just-emerged visual register. Sits at the crisp-and-clean end of the grid, parallel to crisp and new in usage.

Starlight
noun

The integrated visible spectrum of the Milky Way's faint stars — about 500 times dimmer than full moonlight and richly blue-violet at high galactic-latitude viewing angles where dust extinction is minimized. Starlight color refers to the deep-blue night-sky background between the brightest stars on a moonless dark-site night: a saturated, slightly cool deep blue-violet with the optical complexity of integrated multi-stellar Rayleigh-scattered atmospheric light.

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.
