Outdoor paint for wooden surface in strong/vibrant colours?

I want to paint the fence around my garden in strong, bright colours, but when I was looking at outdoor wood paint at the DIY store, they’re all pretty toned down. Is it possible to use other paint or will that just fade and/or peel off?

I don’t mind having to repaint again next year, so I’m not looking for Ronseal grade treatment-paint.
