Well, it kinda annoyes me. I'm using the default style, thats a green template. And the pink google ads dont look quite good on that. I'd suggest to change the colour of the ads.
LOL how about he achieved what he wanted i.e. make them stand out. Some money needs ideally to be earned to cover costs you know, we're not just hear to give all of you a good time for free. If you;re desperate, write some script like Greasemonkey to change it yourself. Or disable ads altogether.
Ok, i made a mistake, the ads keep changing colours :S Sorry bout this. And it was just a suggestion. Nothing wrong with that.
