Stately Sashiko

#3c78db
Notes

Stately Sashiko (#3C78DB) 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 (217°, 69%, 55%) 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

Stately
adjective

An adjectival form of state, condition of dignity. Used as a color modifier since the seventeenth century for the deep saturated jewel tones of formal ceremony — the deep blue of a robes-of-state, the deep red of a state-banquet velvet. Sits in the bold-and-formal corner alongside imperial and royal, with slightly less institutional weight.

Sashiko
noun

The Japanese decorative-and-reinforcement stitching technique — sashiko — traditionally white running-stitch on indigo-dyed cloth, used to mend and strengthen working garments since the Edo period. Sashiko color refers to a sashiko-stitched indigo boro mended cloth: a saturated, slightly cool deep blue with the matte finish of multi-bath aizome dye.

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.
