Cherry Zen Sidebox Background Color

[mhodapp1]

This question is for the Cherry Zen template. How do I change the background color for the sideboxes? I have found and changed everything else, I just can't figure out how to change the sideboxes. Thanks in advance. Mike

OK, I think I am getting it figured out finally. I changed the colors on rightsidebox.gif and sidebox.gif to white and this allowed the main background color to show up, even though I wanted white. I'll keep playing around until I get the color I need I guess. It must be a transparency issue in the gif file now.
