I have a blue header, with white content. I now use a skyscraper ad with the same color blue background and border as my header. With yellow text and white URLs, it really looks like the adsense ads are part of my natural site navigation.
To the less sophisticated users, I am certain they often think it's part of the site navigation. I really try to do that; to make the Adsense layout merge into my site naturally, as though they are to pages within my site.
What I have found is that a strong contrasting color can help to draw the eye to the ad, though it should fit in with the color palette of your site. You'll need to test on this, but on my site, which is text-heavy and thus displays as black/blue/purple, making one of the three different text elements red increases the CTR.
border: 333366
background: FFFFFF
link: 000080
url: 008000
text: 000000
They may or may not work as well on your sites as my designs typically have a more subtle color scheme rather than anything that really sticks out. I usually get about a 2% higher CTR with this color scheme than colors that match the site and hide the borders.
