Colors that go with #aae51f
Crimson, Deep Sky Blue and Red 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.

Red #ff0000
shippedRed is paired with #aae51f in 5 real palettes, including Wise's brand system and Gatorade's brand system, as the lead colour.
Plum #dda0dd
complementaryPlum sits directly opposite #aae51f on the wheel — the strongest contrast one hue can give another, so use it small: a button, a link colour, one highlight.
Violet #ee82ee
split-complementshippedViolet is a split-complement of #aae51f: nearly opposite, so it still pops against it, without the vibrating edge of a true complement.
Blue #0000ff
shipped3 real palettes, including Robinhood's brand system and MongoDB's brand system put Blue beside #aae51f, as the supporting colour.
Charcoal #36454f
neutralshippedCharcoal is the body-text near-black for #aae51f: its slight blue cast keeps type crisp beside a warm colour where pure #000 looks heavy.
Gold #ffd700
shippedGold shows up next to #aae51f in 3 real palettes, including Ikea's brand system and Paddle's brand system, as the supporting colour.
