Font color in Posts

I discovered the font color in my Blog posts was not what I expected or wanted and I can't find where to make the change. Here's an example: http://driftlessprairies.org/?p=7095

I'm not sure why the font color in the posts would be different from the pages, but I would like to have these the same. Here's a page example of the font color: http://driftlessprairies.org/?page_id=2007

Thanks for the help!
