Can we use same color and text for blogger post text and google adsense ads. If we put those ads in blog post will adsense team band me(cancel my accout?)?
This is absolutely alright. You won't be banned for it. Infact your CTR might get increased. BTW, who stupid told you that you will be banned from adsense for this act. You will get banned only when there is some illegal and non-tolerable activity on your site. Read adsense TOS and Program policies so that everything regarding adsense could be cleared to you.
Not sure though regarding getting banned if you do that, But sounds like it should be against there TOS, Because hidden Text comes in this case, and this is against TOS i guess. IMO
here is your answer: -make your ads' "headline and link" color same with your link color. usually blue -make your ads' normal article part color same with your article color. usually black -don't make ugly your ads, they shouldnt bother visitors. you can review mine on my sig.
Check out the last update Google policies... and then send an email to Google Adsense Team, here you will get yes you can, no you cannot, all right you CAN, etc etc, but then if you'll get banned, now way, if then if you get a positive response from Adsense Google Team, and the nyou will get banned, you have their email to re send them. My 2 cents
