Handmade Tuff

#13063a
Notes

Handmade Tuff (#13063A) is a deep indigo with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (255°, 81%, 13%) places it in the highly saturated band at a dark 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 lime. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Handmade
adjective

English compound hand + past-participle made — sharing root with make. As a color modifier, handmade implies a neutral-and-hand-built-and-craft quality, the neutral color of Mingei-Japanese-and-Shaker-and-Wedgwood hand-built-and-craft-tradition pottery-and-textile-and-furniture surface-finish. Sits at the neutral-and-traditional end of the grid, parallel to handcrafted and artisanal in usage.

Tuff
noun

Italian tufo, porous-stone — the deep-cool-gray volcanic-ash-and-pumice cemented-rock of Cappadocian and Roman-Volsinian monolithic-architecture quarries. Tuff color refers to a Cappadocian Göreme tuff cliff-cave face in midday sun: a dark cool-gray with the matte finish of welded-and-non-welded pyroclastic flow deposit on hand-carved early-Christian rock-cut church.
