Looking for inspiration

So my nails desperately need repainting, and I want something really pretty, but can't decide where to start. I can stamp, and do dots. Im also tempted to try a gradient, but wouldn't know what colour to use. Anyone got any suggestions?

Why don't you try a skittle manicure? That way you can use five colours at once.   

Neon skittle maybe? Though that might be a bit loud... Thank you
