Hospitable Wold Topaz

#1bc8be
Notes

Hospitable Wold Topaz (#1BC8BE) 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 (177°, 76%, 45%) 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

Hospitable
adjective

Latin hospitābilis, of-the-host — adjectival suffix -able. As a color modifier, hospitable implies a clear-and-cordial-and-welcoming quality where the hue carries the visual register of Bed-and-Breakfast and country-inn warm-cordial-host atmosphere. Sits at the crisp-and-cheerful end of the grid, parallel to welcoming and inviting in usage.

Wold
modifier

Old English wald, forested upland. As a color modifier, wold implies a chalk-upland-and-grass quality, the visual register of Lincolnshire-and-Yorkshire-Wolds chalk-and-limestone open-upland sheep-pasture-and-arable rolling surfaces under big-sky Lincolnshire-Wolds open-country light. Sits at the modifier-and-place end of the grid, parallel to moor and heath in usage.

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.

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.
