Google AdSense first began experimenting with arrows to scroll the ads displayed back in December 2007. It became a confirmed feature in April 2008. Now, people are noticing that the colors of the arrows are being changed.

A WebmasterWorld thread had one publisher notice that "every now and then they'll be highlighted, in my case to match my title color." Others have confirmed seeing this.

I personally could not replicate this on any of my sites, nor have I noticed this on other sites with AdSense.

But if this is indeed a test, it would not surprise me. Most people are missing those ad arrows and maybe Google wants a better way of highlighting them.
