Strong Pansy
Strong Pansy (#573BA0) is a true indigo 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 (257°, 46%, 43%) 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 lime. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Old English strang, firm, vigorous — applied to color since the sixteenth century. Strong red, strong tea: a color at full strength is the maximum saturation the medium can produce. Sits at the saturated mid corner of the grid, parallel to bold in usage but slightly more focused on pigment density than on assertion.
Viola × wittrockiana, the cultivated garden pansy bred in the nineteenth century from wild Viola tricolor. The color refers to the deep purple-blue field of a Pansy Imperial hybrid: a saturated, slightly violet-shifted deep blue with the velvet finish of a five-petaled face. Cooler than amethyst, warmer than indigo, with the cottage-garden weight of a flower that overwinters in mild climates and blooms when nothing else does.
