Update: Google Confirms Adsense Changes Are a Test

Yesterday I posted about the changes Google had made to their Adsense ads. Today, Google confirmed that the changes are part of a test:

"Thanks for your email - as you've mentioned, the change that you saw was part of ongoing testing to improve our ad formats. Such variations are a normal part of our testing process and generally run for short periods of time only. No permanent changes are planned at this time.

To maintain the integrity of ongoing testing, we do not permit publishers to opt out. However, please rest assured that such variations should impact only a very small percentage of your impressions.

We appreciate your patience and understanding as we work to improve our program.

Sincerely,

Stephanie
The Google AdSense Team"

Based on how I read the article it is a very small-scale test by Google and is likely designed to see how or if the changes affect blending techniques and click through rate. The changes are not permanent at this point and will probably not be for some time. After the test is completed the statistics will likely be analyzed and then a decision will be made on their implementation. My best guess is that you will be able to chooses how the "Ads by Goooogle" is shown on your ads, or at the very least, opt out of the colored Google logo.
