Change Blog Background to White?

Hi there. Fantastic plugin that’s been a real help with my site, thanks.

Just wondering if there’s any way to change the colour of the blog post backgrounds to white (with black text) when my site is set to a black background colour?

I raised the question with the theme developer but there is currently no solution with them.

Any help or ideas would be gratefully appreciated.

Mike.
