Dazzling Reykjavík

#2aace2
Notes

Dazzling Reykjavík (#2AACE2) is a true cyan with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (198°, 76%, 53%) 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.

Reykjavík
noun

The Icelandic capital — and the deep blue of Faxaflói Bay and the Bláa Lónið (Blue Lagoon) geothermal waters. Reykjavík color refers to the Blue Lagoon at midwinter: a soft, slightly cool deep blue-green with the optical complexity of silica-rich geothermal water.

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.
