Just a quick shout-out to Microsoft:
I. FUCKING HATE. INTERNET EXPLORER.
That being said, I figured out why some people were getting a red-on-red color scheme: all because IE6 has some kind of issues with the width attribute in one of my div tags.
Yup. Something that every other browser could handle, including earlier versions of IE, broke IE6. Big time.
If you are looking at this site in IE6, do yourself a favor: upgrade.
