Aaron Wall noticed that Google is testing a new AdWords background color that is ever so slightly different from the current one. The current color is #FFF8E7 and the test color is #FAFAE9.

The test color seems a bit darker or muddier to me but I am not sure if that is enough to increase clicks on the ads. Do you think one color is more blended into the organic results than the other? I guess Google is trying to test it.

Here is an animated GIF between the two:

We do not believe it is a colorblind thing because Aaron Wall and I put the two colors through this tool and it didn’t look different to us.

Do you think the new test color is more blended?

Google has tried many colors for the AdWords background, here is the history of those colors:

February 2011 – Back To Yellow:

July 2010 – Pale Purple:

April 2007 – Yellow:

Prior – Blue :

Test of Green May 2008:

They even tested muticolored backgrounds.
