Wholesome Aquamarine

#337d40
Notes

Wholesome Aquamarine (#337D40) is a true green 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 (131°, 42%, 35%) places it in the balanced 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

Wholesome
adjective

An adjectival form of whole — used as a color modifier since the sixteenth century for hues that read as healthy and unadulterated. Wholesome cream, wholesome wheat: moderate saturation combined with the optical impression of a natural origin. Sits at the crisp-bucket alongside genuine.

Aquamarine
noun

An iron-tinged variety of beryl — the gemstone mined from pegmatite veins in Brazil, Madagascar, and the Pakistani Karakoram. Named for the Latin aqua marina, seawater. The color refers to a faceted Santa Maria aquamarine: a clean, slightly green-shifted blue with the gem's high refractive brilliance. Lighter than sapphire, deeper than seafoam, with the gem-trade specificity of a stone graded primarily for color depth.
