Frank Year Topaz

#25c8bf
Notes

Frank Year Topaz (#25C8BF) 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°, 69%, 46%) places it in the balanced band at a mid lightness. It works across type, buttons, and borders, saturated enough to feel deliberate but balanced enough to not fight the rest of the palette. 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

Frank
adjective

From the Old French franc, free, sincere — used as a color modifier since the seventeenth century for hues that read as direct and unhedged. Frank red, frank brown: moderate-to-high saturation combined with optical directness. Sits at the crisp-bucket alongside direct and honest.

Year
modifier

Old English gēar, year. As a color modifier, year implies an annual-cycle quality, the visual register of agricultural-and-pastoral yearly-rhythm seedtime-and-harvest seasonal-cycle pasture-and-arable surfaces under year-long pastoral-and-agricultural sky. Sits at the modifier-and-time end of the grid, parallel to cycle and phase 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.
