Colors that go with #2efe1b
Violet, Deep Sky Blue and Hot Pink 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
complementaryViolet sits directly opposite #2efe1b on the wheel — the strongest contrast one hue can give another, so use it small: a button, a link colour, one highlight.
Deep Sky Blue #00bfff

Hot Pink #ff69b4

Blue #0000ff

Charcoal #36454f

Plum #dda0dd
