What's the chance of seeing some different colour cars this year?

We are used to seeing the Orange cars of TD and WSR.
The red Alfa's and Vauxhall (Okay, Green and Red).
Yellow Seat's.
And Black MG's.

Oh, and suppose we will see a bit of pink again!

I'm hoping that we can see a more colourful selection this year.

Anyone got any colours they would like to see?
