Simply put this javascript in your page directly above where the Google Ad shows. Edit colors in the script, by changing the hex value. Right now the colors are set up for my forum. You can see a preview here. (http://forum.gamerunlimited.com) Enjoy!

Thanks! It comes in handy for changing the color of the ads if the remotely hosting place has em on there, but PLEASE note that you should talk to the owner/admin of the hosting site that places the ad on your pages, because it could be against their TOS to change the colors, thus making it not as visible. So, use this script at your own risk. :)
