Plumb Lent Mint

Latin plumbum, lead — referring to the lead-weighted plumb-line of pre-modern carpentry. As a color modifier, plumb implies a clear-and-vertical-true quality where the hue carries the visual register of gravity-aligned-and-perfectly-vertical surface. Sits at the crisp-and-balanced end of the grid, parallel to level and squared in usage.

Latin Lententide, Lent / spring. As a color modifier, lent implies a Lenten-and-fasting-and-purple quality, the visual register of Roman-Catholic-and-Anglican Lenten-period purple-vestment-and-fast-and-ash-Wednesday liturgical surfaces under Lenten-purple ecclesiastical-vestment candlelight. Sits at the modifier-and-time end of the grid, parallel to advent and easter 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.
