Colors that go with #cafb37

Plum #dda0dd
complementaryPlum sits directly opposite #cafb37 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 #cafb37: nearly opposite, so it still pops against it, without the vibrating edge of a true complement.
Charcoal #36454f
neutralshippedCharcoal is the body-text near-black for #cafb37: its slight blue cast keeps type crisp beside a warm colour where pure #000 looks heavy.
