Plain Crown Topaz
Plain Crown Topaz (#11BAAC) 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°, 83%, 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
Latin planus, flat, level — used as a color modifier since the medieval period for hues that read as undecorated and direct. Plain white, plain blue: moderate saturation, no shift, no surface effect. Sits in the crisp-bucket center, with the implication of restraint rather than absence.
Latin corōna, garland / crown. As a color modifier, crown implies a royal-headpiece-and-coronation quality, the visual register of British-Imperial-State-Crown-and-French-Crown-Jewel hand-set jeweled-and-velvet-and-gilt royal-and-Imperial-coronation surfaces under Imperial-State-Crown-and-French-Crown-Jewel royal-and-Imperial coronation-day light. Sits at the modifier-and-cultural end of the grid, parallel to throne and coronet in usage.
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.
