Unwanted light pink background fill

I have no idea if this is the correct project.. I can never figure out what the module is, because it never has anything to do with a specific module, or I just have no idea...
I have been tearing apart the CSS on my website for a while but cannot figure it out.. Any time I create a new page (does not matter what content type or text format) there is a light pink background around the block where the pages' information is. Example, http://www.irwinfirstumc.org/2013-vbs. The weird thing, any pages I created before, are showing up perfectly normal (example http://www.irwinfirstumc.org/whycometochurch ). I cannot figure out where the page is pulling this weird color.
Can anyone give me any advice on what is going on? I'm not sure what was installed/modified around the time this issue started, or when I first noticed the issue.
