Lilac
Lilac (#A47DAB) is a true violet with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (291°, 21%, 58%) 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 green. For something softer, pull in its analogous neighbors on either side of the wheel. The dusty mid-purple of lilac blossoms (Syringa vulgaris) — muted, slightly pink-leaning, and unmistakably floral. Matches Figma's default `lilac`. CSS has no `lilac` keyword; the closest web-safe stand-ins (plum, thistle, orchid) all drift too pale, so this entry anchors the name to the color most designers actually picture.
