Brilliant Rosemary
Brilliant Rosemary (#52A756) 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 (123°, 34%, 49%) 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 violet. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
From the Italian brillante, sparkling — used as a color modifier since the seventeenth century for hues that read as optically active beyond their literal saturation. Brilliant green, brilliant blue: the implication is luminance combined with the slight sparkle of a high-refractive surface. Sits at the bright-bucket center alongside vivid and bright.
Salvia rosmarinus, the woody-stemmed Mediterranean shrub whose Latin name means dew of the sea for its preference for coastal habitat. The color refers to mature rosemary needles in summer: a deep, slightly muted green with the resinous finish of a leaf full of camphor and eucalyptol. Drabber than basil, warmer than thyme, with the kitchen-and-garden weight of a herb used for poultry, lamb, and remembrance.
