Sits at the neutral-and-traditional end of the grid, parallel to homespun and folksy in usage.

Dust
noun

Fine particulate matter — atmospheric dust from soil weathering, dry-lakebed loess, the micron-scale residue that settles on every surface in any room with air movement. The color refers to fresh undisturbed dust on a piano lid: a soft, slightly muted very pale warm gray with the powdery finish of micron-scale particles. Lighter than ash, warmer than stone.
