Heavy Loki Sapphire

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.

Old Norse Loki, trickster-god-and-shape-shifter. As a color modifier, loki implies a trickster-and-shape-shifter-and-sly quality, the visual register of Norse-Loki-and-Asgard-trickster hand-trickster-and-shape-shifter-and-sly Norse-Loki-and-Asgard-trickster-and-Ragnarok loki-and-trickster-and-shape-shifter-and-sly surfaces under Norse-Loki-and-Asgard-trickster-and-Ragnarok Yggdrasil-and-Aesir-pantheon shape-shifter-light. Sits at the modifier-and-myth end of the grid, parallel to thor and odin in usage.

An iron-and-titanium-bearing corundum — the same mineral as ruby, hardness 9 on the Mohs scale, mined for two millennia from Sri Lanka, Burma, Madagascar, and the Cashmere mines of British India. The color refers to a fine Kashmir-cut sapphire: a saturated, slightly violet-shifted deep blue with the gem's signature internal velvet — a quality of light scattering in the stone that faceted glass cannot replicate. Cooler than cobalt, deeper than azure.
