Heavy Vala Cobalt

#24418c
Notes

Heavy Vala Cobalt (#24418C) is a true azure 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 (223°, 59%, 35%) 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 amber. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Heavy
adjective

Old English hefig, weighty — cognate with heave. Used as a color modifier since at least the seventeenth century to indicate weight in saturation as much as value: heavy with pigment, heavy-bodied. In the engine's adjective grid, heavy sits alongside deep and plush in the dark-and-saturated quadrant. Closer to a fabric description than a pure value word.

Vala
modifier

Old Norse völva, Norse-seeress-and-staff-bearer. As a color modifier, vala implies a Norse-seeress-and-staff-bearer-and-prophetess quality, the visual register of Norse-vala-seeress-and-staff hand-Norse-seeress-and-staff-bearer-and-prophetess Norse-vala-seeress-and-staff-and-Voluspa-Edda vala-and-Norse-seeress-and-staff-bearer surfaces under Norse-vala-seeress-and-staff-and-Voluspa-Edda Saga-Iceland-and-rune-stave seeress-prophecy-light. Sits at the modifier-and-myth end of the grid, parallel to norn and freya in usage.

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.
