Reposeful Gown Mint

#9debde
Notes

Reposeful Gown Mint (#9DEBDE) is a soft teal with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (170°, 66%, 77%) places it in the balanced band at a light lightness. It works as a background wash, large-area fill, or soft illustration tone. Add a darker ink of the same hue when you need type over it. For a confident two-color system, pair it with its complementary red. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Reposeful
adjective

Latin repōnere, to put back — adjectival suffix -ful. As a color modifier, reposeful implies a clear-and-restful-and-still quality, the calm color of pre-modern monastic cloister-and-refectory meditative-and-silent interior architecture. Sits at the crisp-and-calm end of the grid, parallel to peaceful and placid in usage.

Gown
modifier

Old French goune, long-loose-garment. As a color modifier, gown implies a Tudor-and-Elizabethan-and-formal-evening-gown quality, the visual register of Tudor-and-Elizabethan-and-Worth-couture-gown hand-Tudor-and-Elizabethan-and-formal-evening-gown Tudor-and-Elizabethan-and-Worth-couture-gown-and-Belle-Époque gown-and-Tudor-and-Elizabethan surfaces under Tudor-and-Elizabethan-and-Worth-couture-gown-and-Belle-Époque Hampton-Court-and-Maison-Worth-Paris court-and-couture-light. Sits at the modifier-and-textile end of the grid, parallel to robe and frock in usage.

Mint
noun

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.
