What's up with the colors on the site?

I wish I could attach a screenshot of what I'm seeing on the WPMUDev site, especially when I try to read the online manuals. The text is navy and gray with shadow on the navy background, and I can't read anything it says. I'm using Chrome 22.0.1229.94 for Mac, but it looks the same in Firefox 16.0.2 as well. I have to highlight the text to be able to read it. Is this intentional?
