Pitchy Tarbuttite

#353986
Notes

Pitchy Tarbuttite (#353986) is a true blue with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (237°, 43%, 37%) 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 yellow. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Pitchy
adjective

Old English pic, pitch — adjectival suffix -y. As a color modifier, pitchy implies the deep-glossy-black quality of bitumen-and-pine-pitch viscous-residue surfaces, particularly the Norse-and-Viking longship-pine-tar caulking. Sits at the deepest-warm end of the grid, parallel to tarry and warmer than Stygian.

Tarbuttite
noun

Rare zinc-phosphate mineral first described from the Broken Hill lead-zinc deposits of Zambia in 1907, also found at Reaphook Hill in South Australia. Tarbuttite color refers to a deep-violet Broken Hill tarbuttite crystal cluster: a saturated, slightly cool deep blue-violet with the glassy finish of zinc-phosphate mineral. Named for Percy Coventry Tarbutt, an early-20th-century mining-company director.

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.
