Colors that go with mediumseagreen
Charcoal, Midnight Blue and Mustard Yellow 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.

Fuchsia #ff00ff
complementaryFuchsia sits directly opposite mediumseagreen on the wheel — the strongest contrast one hue can give another, so use it small: a button, a link colour, one highlight.
Medium Purple #9370db
split-complementshippedMedium Purple is a split-complement of mediumseagreen: nearly opposite, so it still pops against it, without the vibrating edge of a true complement.
Blue #0000ff
