In a Charedi yeshivah, you can't wear blue

Last year, The Knish posted a picture of the cover of the 2009 calendar made by Yeshivas Rebbenu Chaim Berlin, a major Charedi yeshivah in Brooklyn.

In the midst of a sea of white shirts sat one lone student in a blue top. He was clearly flouting the uniform - what an apikores!

The picture was subject to much ridiculing on the web. Nevertheless, the yeshivah used the same picture to grace its 2010 calendar, just out. But can you spot the crucial difference?
