Change Category sidebox color problem

Hello all,

I have completely gone through the stylesheets and have changed every instance of any category related color and can still not get rid of the gray color. See my site:


This is based on the cars template and I was able to change every other color except the category side box. I have found every instance of the color and changed it as well as any section background color to black “000000”. Does anyone have any ideas where else this could be hiding?





Found it.
