Mourning Pimento Cobalt

#09448d
Notes

Mourning Pimento Cobalt (#09448D) is a deep azure 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 (213°, 88%, 29%) 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 orange. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Mourning
adjective

Old English murnan, to grieve — present-participle of mourn, sharing root with Old Norse morna. As a color modifier, mourning implies the deep-and-funereal-and-formal-and-Victorian-mourning-period black-textile quality, the dark cool-formality of widow's-weeds-and-funeral-procession. Sits at the deep-and-funereal end of the grid, parallel to funereal and sepulchral.

As a color modifier, pimento implies a sweet-red-Iberian-capsicum-and-allspice-berry quality, the visual register of Spanish-and-Jamaican-pimento hand-sweet-red-Iberian-capsicum-and-allspice-berry Spanish-and-Jamaican-pimento-and-allspice-berry pimento-and-sweet-red-Iberian-capsicum surfaces under Spanish-and-Jamaican-pimento-and-allspice-berry Iberian-and-Jamaican-Blue-Mountain Iberian-and-Jamaican-spice-light.

Cobalt
noun

Element Co, atomic number 27 — German Kobold, goblin, named by miners who found the metal interfered with smelting silver ore. Cobalt blue is the cobalt-aluminate pigment introduced by Louis Jacques Thénard in 1802: a saturated, slightly green-shifted deep blue with the matte finish of mineral pigment in oil. Cooler than ultramarine, warmer than prussian, with the painter's weight of a pigment used by Renoir, Van Gogh, and Cézanne.
