Dazzling Konjō

#289aed
Notes

Dazzling Konjō (#289AED) is a true azure with a neon character. It sits at the high-saturation edge of its family. Use it sparingly, as signage, accent, or highlight against darker surfaces. Its HSL profile (205°, 85%, 54%) places it in the highly saturated band at a mid lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. 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

Dazzling
adjective

The progressive participle of dazzle, to overwhelm with brightness — used as a color word since the seventeenth century for hues that read as intense enough to be momentarily blinding. Dazzling white, dazzling pink: the implication is luminance pushed to the extreme. Sits at the bright-bucket extreme alongside electric.

Konjō
noun

Japanese konjō (紺青) — deep blue-azure, the saturated deep navy used in Edo-period samurai inner robes and Buddhist mandala backgrounds. Distinct from konpeki by its slightly cooler shift toward navy. The color refers to a konjō-dyed silk: a saturated, slightly cool dark blue with the satin finish of multi-bath dyed silk.
