Earnest Chionodoxa

#303d9e
Notes

Earnest Chionodoxa (#303D9E) 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°, 53%, 40%) 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

Earnest
adjective

Old English eornost, seriousness, zeal. Used as a color modifier since the nineteenth century for hues that read as committed but unshowy — the working blues of denim, the deep greens of Quaker meetinghouses. Sits in the bold-and-quiet corner of the grid, slightly less luminous than resolute and slightly less institutional than imperial.

Chionodoxa
noun

Mediterranean Glory-of-the-Snow (Chionodoxa luciliae) — a small Anatolian-mountain spring-flowering bulb whose name combines Greek khión (snow) and dóxa (glory). Chionodoxa color refers to a freshly opened Chionodoxa luciliae six-tepalled star: a saturated, slightly cool deep blue-violet with the velvet finish of small radiating tepals around a paler center. Blooms while alpine snow lingers in patches.

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.
