I don't know if you have try this my adsense result was not going well but after i change some of the colour the google ad on my blogs, the result change, the boder red, the back ground yellow, and url kink black they say there is this attraction between human, red and yellow. so i tried it and it work for me i want you to try it too and tell me your result. You must work for traffic too don't change the colour and go to sleep good luck
Most of the time on mine I use `open air` so there`s no background. I think the more the ads blend in, the better. That works for me, but of course every one is different.
Why not rotate your adsense , though i would say default ad colours is always the best, the more you try to make the ads look like content, the more visitors try to ignore them. Also check this out Randomize your Adsense Ad Colour
I commonly do this if( rand( 0, 1000) > 500 ){ //display ads color sheme 1 }else{ //sheme 2 } //you can do for more than 2 shemes $arrayOfAdsenseCodes = array( 1 , 2, 3 , 4, 5); $numberOfSehemes = count ( $arrayOfAdsenseCodes ); $pick = rand( 1, $numberOfSehemes * 100 ); $addIndex = (int) ($pick / 100); $theAdd = $arrayOfAdsenseCodes[$addIndex - 1 ]; PHP: For each add you have a channel and after few days you will know which to pick, if 2 of them makes same money , there may be a case that rotating different themes attracts more click
