Lost theme background color

Please help.

I’m using the red city wp theme but I think I screwed something up. I submitted site to Technorati and they want you to put a line of code on front page. I pasted it in header and a link to my Technorati “about me” page showed up on top of my blog’s first page. I didn’t want it to show so I took code out of header and put in footer which didn’t do anything so I removed it from footer and put back in
header.

Anyway, since doing this, when I first call up my site, colors are okay until I click on something like a category. Then I lose the background color.

I’m new to this, so I don’t know if this is something I did or if it
has something to do with the wp update to 2.6.3 which I did thru Blue
Host. How do I get my background color back?

My site is https://www.x-nygal.com so you can see what I mean.

Thanks.
