Plum #dda0dd
complementaryPlum sits directly opposite #a9c615 on the wheel — the strongest contrast one hue can give another, so use it small: a button, a link colour, one highlight.
Charcoal #36454f
neutralshippedCharcoal is the body-text near-black for #a9c615: its slight blue cast keeps type crisp beside a warm colour where pure #000 looks heavy.
Cornflower Blue #6495ed

Red #ff0000
