    One of the reasons Google might be using this light blue/purple color is for orientation reasons. Orientation is a search behavior that everyone does without realizing it. People orient on SERPs using the top vertical bar (background), and it’s a natural eye flow to ads (which are also used to orient on a SERP) if the background color is the same.

    I like to keep records of Google’s color choices. Believe it or not, since they are so well tested, I like to use (and test them) on client websites with matching color schemes. Takes some of the guesswork out of color selection.
