Lists are formatting by themselves–find nothing in CSS to show why

The lists in my content area are a different size font and different color than the rest of the center content. (Site The Editor’s Blog. A post to look at–Self-Editing Tips.

I find nothing in my stylesheet showing where lists for the content or body area are being formatted, whether ordered or unordered. Lists in the sidebars are formatted and that formatting works correctly.

Is there a place other than the stylesheet where this is coming from? Or, is there a default if no formatting is specified in the stylesheet? I want to keep the font size and color the same as for the rest of the post content.

Suggestions? Thanks in advance.
