Symmetrical Stoa Mint

#a4f8de
Notes

Symmetrical Stoa Mint (#A4F8DE) is a soft teal with a pastel character. It reads calm and airy, with enough chroma to feel intentional rather than washed out. Its HSL profile (161°, 86%, 81%) places it in the highly saturated band at a light lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. 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

Symmetrical
adjective

Greek symmetría, due-proportion — adjectival suffix -al, derived from sym-metron (with-measure). As a color modifier, symmetrical implies a clear-and-balanced-and-mirrored quality where the hue carries the visual register of bilateral-or-radial proportional symmetry. Sits at the crisp-and-balanced end of the grid, parallel to balanced and aligned in usage.

Stoa
modifier

Greek stoa, Greek-colonnaded-walkway. As a color modifier, stoa implies a Greek-and-Athens-colonnaded-walkway quality, the visual register of Athenian-Stoa-of-Attalos hand-built colonnaded-walkway-and-marketplace stoa-and-arcade-and-bouleuterion classical-Greek architectural surfaces under Athenian-Stoa-of-Attalos colonnaded-walkway light. Sits at the modifier-and-architecture end of the grid, parallel to agora and forum 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.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
