Colors that go with #221102
Blue Violet, Charcoal and Royal Blue lead the list. Each partner is a real named colour with the reason it works — a wheel relationship, a neutral that carries it, or a pairing lifted from a palette or brand system that actually shipped — and every pair opens in the palette tool.
Blue Violet #8a2be2
triadicshippedBlue Violet completes a triad with #221102 — three hues spaced evenly round the wheel, the classic way to get energy into a palette without a clash.
Charcoal #36454f
neutralshippedCharcoal is the body-text near-black for #221102: its slight blue cast keeps type crisp beside a warm colour where pure #000 looks heavy.
Royal Blue #4169e1

Steel Blue #4682b4
