Pitchy Toadflax

#170f35
Notes

Pitchy Toadflax (#170F35) is a deep indigo with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (253°, 56%, 13%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. 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.

Toadflax
noun

Eurasian Linaria vulgaris and L. purpureasnapdragon cousins with hooded violet-and-yellow flowers naturalized across temperate roadsides and waste-ground. Toadflax color refers to a fully bloomed Linaria purpurea spike: a saturated, slightly cool deep blue-violet with the matte finish of dense small two-lipped snapdragon-form flowers. The Old English name refers to the linear flax-like foliage of the wild Linaria genus.
