Colors that go with #a21bb1
Denim, Forest Green 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.
Denim #1560bd
shippedDesigners have shipped Denim with #a21bb1: 4 real palettes, including Peacock and Hasbro's brand system, as the supporting colour.
Forest Green #228b22
complementaryForest Green sits directly opposite #a21bb1 on the wheel — the strongest contrast one hue can give another, so use it small: a button, a link colour, one highlight.
Teal #008080

Charcoal #36454f
neutralshippedCharcoal is the text near-black for #a21bb1: softer than #000 and cool enough to feel like part of the same palette.
Olive Green #808000

Medium Violet Red #c71585
