Homemade Bonechar

#0a021e
Notes

Homemade Bonechar (#0A021E) 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 (257°, 88%, 6%) 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

Homemade
adjective

English compound home + past-participle made — sharing root with make. As a color modifier, homemade implies a neutral-and-handcrafted-and-domestic quality, the neutral color of American-and-English-cottage hand-made-and-home-craft household-textile-and-pottery surface-finish. Sits at the neutral-and-traditional end of the grid, parallel to handmade and handcrafted in usage.

Bonechar
noun

Bone-black pigment produced by the dry-distillation of animal bones in an oxygen-free retort — the deepest blue-black of the carbon-black pigment family, used as the Frankfurt black of Dutch Golden-Age oil painting. Bonechar color refers to a bone-black-thinned oil glaze in a Rembrandt 1660s Self Portrait: a saturated, slightly cool deep black with the matte finish of bone-char-and-poppy-oil glaze on aged linen canvas.
