Squared Advent Mint

#63967f
Notes

Squared Advent Mint (#63967F) is a true teal with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (153°, 20%, 49%) places it in the muted band at a mid lightness. It works across type, buttons, and borders, saturated enough to feel deliberate but balanced enough to not fight the rest of the palette. For a confident two-color system, pair it with its complementary magenta. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Squared
adjective

Latin quadrātus, four-sided — past-participle of square. As a color modifier, squared implies a clear-and-rectilinear-and-orthogonal quality where the hue carries the visual register of right-angle architectural-and-grid alignment. Sits at the crisp-and-balanced end of the grid, parallel to aligned and plumb in usage.

Advent
modifier

Latin adventus, arrival. As a color modifier, advent implies a December-Pre-Christmas-and-purple quality, the visual register of Roman-Catholic-and-Anglican Advent-period purple-and-pink-vestment-and-wreath-and-candle liturgical surfaces under Advent-period candlelit-purple-and-pink ecclesiastical light. Sits at the modifier-and-time end of the grid, parallel to yule and easter 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.
