I got this email a day or two ago. I think this only applies to the default palette for adsense ads, but I wanted to share this with everyone, in case you didn't get the email...
Hello,
We're writing to let you know about a coming change to the
appearance of your Google ads. Your ads currently display the
default Google color palette, Seaside (formerly known as Mother
Earth). In the near future, we plan to update the default palette to
Open Air, a new palette containing the same set of colors, but
without the blue border. We've found that many publishers prefer
the cleaner look of this palette and have also seen that a
blended color palette performs better for them -- attracting user
interest while still maintaining the distinction between ads and
content with the 'Ads by Google' label.
Please note that this change will only affect your ad units where your
ad code does not specify colors.* For all other units, your color
selections will be retained.
You can view the new Open Air palette by taking these steps:
1. Log into your AdSense account at
http://www.google.com/adsense
2. Go to the 'AdSense Setup' tab.
3. Click the 'Color Palettes' link.
4. From the color palettes dropdown, select 'Open Air'. The
example ad will update to show the new palette.
If you'd prefer not to use Open Air, you can change your ad
colors by following the steps detailed in our Help Center:
http://www.google.com/support/adsense/bin/answer.py?answer=9981.
Please keep in mind that if you choose to change your ad
colors, you'll need to generate new ad code using the new colors
and replace the code that's currently on your pages.
If you don't choose to update your ad code, your ads will begin
displaying the Open Air palette within the next 10 days. Please
let us know if you have any questions or concerns.
Sincerely,
The Google AdSense Team
*You can check if your ad code specifies colors by looking for any
"color" tags such as "google_color_border" or "google_color_bg"
in your HTML. If you find any color tags in the code for an ad
unit, this unit will not be affected by the change.
