#6b16dargb(107, 22, 218)hsl(266, 82%, 47%)oklch(0.477 0.253 292.7)Olive Green, Denim 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.
Olive Green sits directly opposite #6b16da on the wheel — the strongest contrast one hue can give another, so use it small: a button, a link colour, one highlight.
Designers have shipped Denim with #6b16da: 3 real palettes, including Linkedin's brand system and Unilever's brand system, as the lead colour.
Royal Blue is #6b16da's neighbour on the wheel, so the two read as one family — use it for hover states, gradients and secondary surfaces.
Teal completes a triad with #6b16da — three hues spaced evenly round the wheel, the classic way to get energy into a palette without a clash.
Forest Green is a split-complement of #6b16da: nearly opposite, so it still pops against it, without the vibrating edge of a true complement.
Charcoal is the text near-black for #6b16da: softer than #000 and cool enough to feel like part of the same palette.
Designers have shipped Cobalt Blue with #6b16da: two real palettes: Zillow's brand system and Unilever's brand system, as the supporting colour.
Designers have shipped Deep Sky Blue with #6b16da: two real palettes: Kraken's brand system and Render's brand system, as the accent.
