Google Search New Design?

It looks like the Google Designers have been at it again with a new(ish) blue colour appearing occassionally on the search page and the search results page. Apparantly, according to the SEO roundtable blog, this has been “out” for sometime (about November last year) – however it is beginning to be seen more often. No idea at the moment when Google (or if Google) will launch this. But it looks nice and fresh to me.
