Duplicate Page Content Issues

I think you should use canonical link tag here, that should solve your problem. Here is the link where you can find out more:

It's a bit tricky - we actually count something like 90%+ duplicated content as "duplicate", so we may be giving you false alarms on this particular example. My gut reaction is that they're thin pages - they look fine on the surface, but there's very little text content for Google to parse, and I think the overall content is very light even from a usability perspective. From a pure SEO perspective, if you had a lot of these very similar pages, you could run into some trouble.
Honestly, at this point, you just don't have the authority (link profile, etc.) to support 10,000 products and the roughly 18,000 pages Google has indexed on your site. In the extreme case, you could run into a Panda penalty, but overall it's just an issue of dilution. Basically, you don't have the ranking power to support that many products, especially if Google perceived the content as thin.
It's a balancing act, but I'd consider potentially NONINDEX'ing some of your thinner product offerings while you build up unique content for at least your top sellers. This doesn't have to be all-or-none. It may be that a couple hundred or even a few dozen products account for 90% of your sales, so start with those. Meanwhile, de-index some of your weakest content, and let the rest build up over time.
Of course, there may be other issues at play, like actualy URL-based duplicates, that could be tackled before you start removing products from the Google index. Again, it's a balancing act. You could also use rel=canonical, but my gut reaction is that it's borderline for the cases you're showing here. These aren't true duplicates, and are separate products. It's just a matter of whether you want Google to see them yet or not.
