Smooth Hawkseye

#05bcc7
Notes

Smooth Hawkseye (#05BCC7) 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 (183°, 95%, 40%) 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 red. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Smooth
adjective

Old English smōþ, level, polished — used as a color modifier since the seventeenth century for hues that read as continuous without texture or break. Smooth tan, smooth gray: moderate saturation combined with optical evenness. Sits in the crisp-bucket alongside even.

Hawkseye
noun

A blue-gray variety of tigereye quartz — colored by crocidolite asbestos inclusions that scatter light into a chatoyant band like the eye of a raptor. The color refers to a polished Hawkseye cabochon: a soft, slightly cool deep blue-gray with the optical complexity of chatoyant silicate fibers.
