Plain Robe Mint

Latin planus, flat, level — used as a color modifier since the medieval period for hues that read as undecorated and direct. Plain white, plain blue: moderate saturation, no shift, no surface effect. Sits in the crisp-bucket center, with the implication of restraint rather than absence.

Old French robe, long-flowing-garment. As a color modifier, robe implies a long-flowing-and-academic-and-judicial quality, the visual register of Oxford-Cambridge-academic-and-judicial-robe hand-long-flowing-and-academic-and-judicial Oxford-Cambridge-academic-and-judicial-robe-and-monastic-habit robe-and-long-flowing-and-academic surfaces under Oxford-Cambridge-academic-and-judicial-robe-and-monastic-habit Senate-and-Inns-of-Court-and-cathedral-cloister Trinity-Senior-Common-Room-light. Sits at the modifier-and-textile end of the grid, parallel to gown and cope 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.
