White border on white background with AdSense - is that ok?

"Ads by Google" become invisible...

[Philarmon]

Hello!

I'm new to AdSense and playing around with the color schemes. The best looking one for my site would be the one without borders (white borders on white background). I want to use the Leaderboard. When i set up the colors on the AdSense Settings page, i still see the "Ads by Google" link - it have black color. But when i paste the code to my website, the link disappears (it's white there). So now i'm unsure if i could get a penalty for invisible text on the site?

Also, do someone have expirience with no-border ads - it is good or bad regarding the CTR?

Thanks for any help!

As long as you do not modify the AdSense generated code, you will not be penalized.
