Resonant Wend Royal

#166fec
Notes

Resonant Wend Royal (#166FEC) 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 (215°, 85%, 51%) 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 amber. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Resonant
adjective

Latin resonāns, echoing — present-participle of resonate, sharing root with sonance. As a color modifier, resonant implies a saturated-and-deep-vibrating quality where the hue carries low-frequency visual richness. Sits at the bold-and-resonant end of the grid, parallel to sonorous and resounding in usage.

Wend
modifier

Old English wendan, to-turn-or-go. As a color modifier, wend implies a winding-and-turning-and-meandered quality, the visual register of pilgrim-path-and-river-wend hand-winding-and-turning-and-meandered pilgrim-path-and-river-and-Roman-road wended-and-winding-and-turning-and-meandered surfaces under pilgrim-path-and-river-and-Roman-road Camino-and-Pennine-Way-and-Kumano hilltop-pilgrim-light. Sits at the modifier-and-mood end of the grid, parallel to drift and roam in usage.

Royal
noun

The blue of European royal court dress and regalia from the late seventeenth century forward — the color of British peers' robes, French royal sashes, the lining of the crown-jewel cases. The color refers to a saturated, slightly violet-shifted blue with the matte finish of velvet or melton wool dyed to maximum intensity: deeper than cornflower, warmer than ultramarine, with the heraldic weight of a color reserved for monarchs and the official Crown.
