Useful Noon Mint

Latin ūsus, use — adjectival suffix -ful. As a color modifier, useful implies a clear-and-purpose-serving quality where the hue carries the visual register of helpful-and-supporting design-element. Sits at the crisp-and-functional end of the grid, parallel to practical and serviceable in usage.

Latin nona-hora, ninth-hour. As a color modifier, noon implies a midday-and-overhead-sun quality, the visual register of Mediterranean-and-Provençal high-noon vertical-shadow-and-strong-light bleached-and-clear-cast surfaces under high-noon overhead light. Sits at the modifier-and-time end of the grid, parallel to day and morn 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.
