Defined Hall Mint

Latin dēfīnīre, to set bounds — past-participle of define. As a color modifier, defined implies a clear-and-edge-distinct-and-precise quality where the hue carries the visual register of sharp-bounded-and-clearly-delimited surface. Sits at the crisp-and-clear end of the grid, parallel to crisp and sharp in usage.

Old English heall, large-room / mansion. As a color modifier, hall implies a great-room-and-banquet quality, the visual register of Hampton-Court-and-Westminster hand-built timber-roof-and-stone-pillar great-hall ceremonial-and-dining surfaces under Tudor-and-Plantagenet great-hall ceremonial-feast candlelight. Sits at the modifier-and-place end of the grid, parallel to manor and court in usage.

The genus Mentha — peppermint, spearmint, apple mint, water mint — the cooling herb whose menthol gives it that quality at the molecular level. The color refers to fresh peppermint leaves before drying: a clean, slightly cool green with the matte finish of trichome-rich leaf surface. Lighter than basil, cooler than parsley, with the mojito-and-Pimm's association of a herb tied to summer drinks across two continents.
