So, without further rambling, let's show you what's been done.
I quite like this. It's simple, but I think this is possibly my favourite paint theme. I love how the orange and purple go together, but I also think the shape of the cars, especially the right hand side one, allow this theme to come off brilliantly. It's not easy to notice, but there's a gradient affect on the purple as well, as it shifts from dark to light.
