Strong Pitta
Strong Pitta (#643BBE) 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 (259°, 53%, 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 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.
Asian-and-Australasian Pittidae family — a dozen species of forest-floor passerines with brilliantly colored plumage including the deep-blue Indian pitta (Pitta brachyura) and blue-winged pitta. Pitta color refers to the dorsal-feather field of Pitta brachyura: a saturated, slightly cool deep blue-violet with the iridescent satin finish of structurally colored feather barbs. The genus name comes from the Telugu pitta, meaning small bird.
