Beer, in Green Bottles

After a long dry spell, I've taken to having a beer or two occasionally. My preference seems to run toward imports in green bottles: Beck's, St. Pauli Girl, Stella Artois, Heineken & Tsingtao. They all taste similar to me, and very different from most other beers. So I am wondering if these beers really are similar, or whether I am just seeing green.
