Cyan is an energetic, youthful green blue that should be used to brighten up your design. It's great for feminine colors because it can tone down its electric character when paired with deeper pinks and teals in more sultry color palettes like dark purples or burnt oranges/yellow golds (I know this seems impossible but trust me!).
Cyan also works well as a contrast against deep greys; pair them together on one side of the page while using lighter shades framing them from afar - perfect bedtime reading material!
