Gallant Moonlight

#303ea0
Notes

Gallant Moonlight (#303EA0) 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 (233°, 54%, 41%) 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 amber. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Gallant
adjective

Old French galant, brave / charming — present-participle of galer (to make merry). As a color modifier, gallant implies a saturated-and-chivalrous-and-confident quality, the deep-rich color of Three-Musketeers and Cyrano-de-Bergerac swashbuckling adventure tradition. Sits at the bold-and-chivalrous end of the grid, parallel to valiant and heroic.

Moonlight
noun

The spectrally cool reflected sunlight of a full moon — about 400,000 times dimmer than the sun and slightly redder than direct sunlight due to lunar regolith reflectance, but perceived by dark-adapted scotopic vision as deep blue-violet. Moonlight color refers to a clear-sky landscape under full moonlight as photographed long-exposure: a saturated, slightly cool deep blue-violet with the optical complexity of Purkinje-shifted scotopic-perception lighting.

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.
