Why Are Rich Snippet Stars Red On Google?

[Ubique]

I'm using RDFa rich snippets markup on my site and on Google's Structured Data Testing Tool the 5 stars come up in yellow in my listing.

On the web today I checked on indexing progress and the stars are 'red' in the listings - any idea why this might be? Is Google switching them over universally or is it something else?

Hi,

Did you ever find the answer to this question? I'd be interested to know as I'm tackling RSs myself at the moment.
