Candy Coloured Gradient Nails

Today I tried a gradient for the first time, and here's the result:

I love how these colours fit together, they kind of remind me of an ocean sunset. They are really bright and cheerful colours, but not in a too flashy kind of way, if you know what I mean.

I made this gradient using a sponge: 
First you paint your nails in a base colour (the lightest colour of your bunch, normally).
Then you paint the colours onto the sponge, and dip the sponge onto your nails. Then you dip it a bit up and down, so the colours mingle a bit. After that, you put a topcoat on to make the colours blend even better.

Here's a tutorial I found, which shows very nicely what you should do :)
