Colors that go with #af241d
Royal Blue, Steel Blue and Teal 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.
Royal Blue #4169e1
triadicshippedRoyal Blue completes a triad with #af241d — three hues spaced evenly round the wheel, the classic way to get energy into a palette without a clash.
Steel Blue #4682b4

Teal #008080
complementaryshippedTeal sits directly opposite #af241d on the wheel — the strongest contrast one hue can give another, so use it small: a button, a link colour, one highlight.
