Blue Editor Fields

Hi, first of all, this is one of the best themes I've ever seen. Really elegant and user-friendly.

My question is whether there is any way to turn of the blue background in my FCKeditor fields. The normal, drupal text edit fields are white, but the FCKeditor fields go from white to dark blue as you scroll down, which makes it hard to read text as you enter it. Is there any way to change this to just white? Thanks so much.
