I know some have been curious about the color difference between blueberry and petrol. I somehow (?) managed to get a petrol spy off of Saks.com (!!!) last week. I don't know where it came from, it just popped up on the site and I snagged it. Not sure yet whether I get to keep it. Anyway, here are some side-by-side action shots of the petrol regular spy and blueberry baby spy. The blueberry definitely has more purple/navy undertones, while the petrol is a little more gray/green. Enjoy!
