Default Strange film in airlock

I brewed two five gallon batches this past weekend and fermentation seemed to be going just fine, but when i checked on the beer this evening I noticed a strange, lightly tinged brownish green film on the inside of the airlock. I have been brewing for about five years and this is the first time that anything like this has happened. The beer seems to be alright. Has anyone ever seen anthing like this before? I swapped out the airlocks with a freshly sanitized one, but I always fill my airlocks with starsan so I am not sure what could possibly be growing in there.

Perhaps a small amount of krausen blow out into the airlock..
