Color is the only variation for this test -- not image vs text only; or different placement.
Same ad unit shown in the same section of the site in the same placement (my Adsense channels are broken down by topics and by ad units so I know what ad unit in what section of the site in what placement are working), but different colors
The thing being tested is the color scheme alone. One is for the current color scheme I have and the other is for a different color scheme
