Heavy Seth Royal

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.

Egyptian Set, god-of-storms-and-desert-chaos. As a color modifier, seth implies a desert-storm-and-chaos-god quality, the visual register of Egyptian-Seth-and-Ombos-temple hand-desert-storm-and-chaos-god Egyptian-Seth-and-Ombos-temple-and-Osirian-conflict seth-and-desert-storm-and-chaos-god surfaces under Egyptian-Seth-and-Ombos-temple-and-Osirian-conflict Western-Desert-and-storm-cloud red-desert-storm-light. Sits at the modifier-and-myth end of the grid, parallel to horus and ptah in usage.

The blue of European royal court dress and regalia from the late seventeenth century forward — the color of British peers' robes, French royal sashes, the lining of the crown-jewel cases. The color refers to a saturated, slightly violet-shifted blue with the matte finish of velvet or melton wool dyed to maximum intensity: deeper than cornflower, warmer than ultramarine, with the heraldic weight of a color reserved for monarchs and the official Crown.
