An interesting article from WIRED magazine as they do some tests on different colored beer bottles. Clearly Brown still wins. Details from WIRED:
Maybe this picture didn’t turn out as well as I liked. All of these UV beads start off as white and then change colors when exposed. In this picture, one of the green bottles just had one yellow turning bead under it. Not sure why. But you can clearly see that the beads under the brown glass bottles didn’t change colors. Oh, beads in the plastic bag also turned colors. So, from this experiment brown glass bottles block UV light but green and clear do not.
