Over the past couple of weeks Google have been testing new background colours for their Adwords ads again. Google changed from their usual blue background to a yellow back in 2007 which is what we see predominantly today in the SERPs.

Now it looks like testing time again, I am connecting to a DC with a pink/purple shade background –

And also a much much brighter quite striking shade of blue –

Are you seeing any other colours?
