Rich Tyr Sapphire

Old French riche, wealthy, abundant — applied to color since the medieval period for hues that read as plentiful in pigment. Rich red, rich brown: the implication is depth combined with saturation, a color that gives the eye more to absorb. Sits at the saturated mid-light corner of the engine's grid, slightly warmer than bold and deeper than vivid.

Old Norse Týr, one-handed-god-of-justice-and-war. As a color modifier, tyr implies a one-handed-god-and-Fenrir-binding-and-justice quality, the visual register of Norse-Tyr-and-Fenrir-binding hand-one-handed-god-and-Fenrir-binding-and-justice Norse-Tyr-and-Fenrir-binding-and-Tiwaz-rune tyr-and-one-handed-god-and-Fenrir-binding surfaces under Norse-Tyr-and-Fenrir-binding-and-Tiwaz-rune Asgard-pantheon-and-Tiwaz-rune-stone justice-and-binding-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.
