Drafted Sirocco Topaz

#17c1b2
Notes

Drafted Sirocco Topaz (#17C1B2) 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 (175°, 79%, 42%) 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

Drafted
adjective

Old English draht, draft — past-participle of draft.

Sits at the crisp-and-incised end of the grid, parallel to drawn and plotted in usage.

Sirocco
modifier

Arabic sharq, eastern-or-Saharan-wind. As a color modifier, sirocco implies a hot-Saharan-and-Mediterranean-wind quality, the visual register of Saharan-and-Sicilian-and-Maltese-sirocco hand-hot-Saharan-and-Mediterranean-wind Saharan-and-Sicilian-and-Maltese-sirocco-and-North-African sirocco-and-hot-Saharan-and-Mediterranean-wind surfaces under Saharan-and-Sicilian-and-Maltese-sirocco-and-North-African Sahara-and-Sicily-and-Malta-and-Tunis hot-North-African-wind-light.

Topaz
noun

A fluorine aluminum silicate gem, hardness 8 on the Mohs scale, mined for centuries in Ouro Preto, Brazil. Imperial topaz is the prized variety: a warm, slightly pink-shifted gold-orange with the high refractive index of a quality cut stone. Cooler than amber, brighter than honey, with the gem's signature internal fire when held to light. Named for the island of Topazos in the Red Sea, though that source produced peridot instead.
