Are there bluish-blacks in one scene of Superbad?

[Mr_Bester]

I was watching Superbad for the second time last night, both times in one scene the blacks are suddenly blue. It happened both times I watched. It's the scene towards the end when Seth and Evan are in his basement. This is the only place in the whole movie where this happens.

Is it on all disks, or did I end up with a bad one? It's hard to figure out how it would only be on my disk though.

I did search, but couldn't find anything.
Thanks
