Colors that go with #f6ff00
Violet, Plum and 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.
Violet #ee82ee
split-complementshippedViolet is a split-complement of #f6ff00: nearly opposite, so it still pops against it, without the vibrating edge of a true complement.
Plum #dda0dd
complementaryPlum sits directly opposite #f6ff00 on the wheel — the strongest contrast one hue can give another, so use it small: a button, a link colour, one highlight.
Blue #0000ff
shippedBlue is paired with #f6ff00 in 3 real palettes, including Robinhood's brand system and Bumble's brand system, as the supporting colour — a combination designers have actually shipped, not a computed rotation.
Charcoal #36454f
neutralshippedCharcoal is the body-text near-black for #f6ff00: its slight blue cast keeps type crisp beside a warm colour where pure #000 looks heavy.
Deep Pink #ff1493
shippedDeep Pink is paired with #f6ff00 in 3 real palettes, including Arcade and JetBrains's brand system, as the lead colour — a combination designers have actually shipped, not a computed rotation.
Deep Sky Blue #00bfff
split-complementshippedDeep Sky Blue is a split-complement of #f6ff00: nearly opposite, so it still pops against it, without the vibrating edge of a true complement.
Lime Green #32cd32
analogousshippedLime Green is #f6ff00's neighbour on the wheel, so the two read as one family — use it for hover states, gradients and secondary surfaces.
Amber #ffbf00
shippedAmber is paired with #f6ff00 in two real palettes: Gumroad's brand system and Binance's brand system, as the accent — a combination designers have actually shipped, not a computed rotation.
