what I sometimes do with adsense, is make some of my adds match colors exc. (like yours), but also put one add button that is completely off the color theme (like pink), and looks blatantly like an add. It may not look so great, but if your want people looking at the add, this has worked for me. (and this way the adds that blend in well will be more likely to be clicked on because people will expect that neon pink adsense button to be the only add)
ok so i talked to google and thay said you can have to Google accounts on a page If a website is in compliance with our program policies (http://www.google.com/adsense/policies ) and the company or owner has given you permission to display ads on their site, you’re welcome to place your ad code on the same pages as the other publisher's ad code. Please keep in mind that it is necessary to contact your web hosting company or the owner of the website to obtain permission to display ads on their pages. Additionally, please be aware that every AdSense publisher is responsible for the content of any website on which their ad code is placed. If a website is found in violation of our program policies, we'll notify any publisher(s) whose ad code is on the website, and ask that they each remove their Google code from that site.
