[SOLVED] Sticky Background Color

Really. This theme was written for the blogging idiot...like me. I am so brand new to this my eyes aren't even opened yet - only two days old! And yet, I'm blogging! I mentioned this before, Flynn, but I will have to wait until the first of the month to donate...but I will.

Also, I love the "Show Off Theme". I'll post my site soon too, but for now I'm still tweaking. I made my first post a sticky and there's a grey background color that I'd like to lose. I like the sticky icon in the corner and that's all I want. Can I change the color to match the background color of the page?
