Resolute Lāzhuward

#1f6dbd
Notes

Resolute Lāzhuward (#1F6DBD) is a true azure with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (210°, 72%, 43%) 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 orange. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Resolute
adjective

From the Latin resolutus, unwavering — used as a color modifier in literary contexts for hues that read as committed and unmoving. Resolute blue, resolute green: the saturation is full, the hue holds its position without shifting under different light. Sits in the bold-bucket center alongside strong and true, with slightly more focus on stability than presence.

Lāzhuward
noun

The Persian word for lapis lazuli — the etymological source of every Western language's word for azure (Arabic al-lāzaward → Old French azur → English azure). Lāzhuward names the stone mined from the Sar-e-Sang valley of Afghanistan. The color refers to a polished Afghan lapis cabochon: a saturated, slightly cool deep blue with the matte finish of high-grade lapis.

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.
