Resolute Yarn Sapphire

#3c7ad9
Notes

Resolute Yarn Sapphire (#3C7AD9) 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 (216°, 67%, 54%) 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

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.

Yarn
modifier

Old English gearn, spun-thread. As a color modifier, yarn implies a hand-spun-thread-and-skein quality, the visual register of hand-spun-yarn-skein hand-spun-and-skeined wool-and-cotton-and-linen hand-spun-yarn-and-skein surfaces under hand-spun-and-skeined yarn-and-skein workshop-light. Sits at the modifier-and-texture end of the grid, parallel to spun and knit in usage.

Sapphire
noun

An iron-and-titanium-bearing corundum — the same mineral as ruby, hardness 9 on the Mohs scale, mined for two millennia from Sri Lanka, Burma, Madagascar, and the Cashmere mines of British India. The color refers to a fine Kashmir-cut sapphire: a saturated, slightly violet-shifted deep blue with the gem's signature internal velvet — a quality of light scattering in the stone that faceted glass cannot replicate. Cooler than cobalt, deeper than azure.

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.
