Can the color of the Command Bar be changed?

When you open up a window to show the contents of a folder, just below

the usual Menu Bar is the Command Bar with menus like "Organize" and

"Views."

That Command Bar has a sickly blue-green color.

Is there any way to change the color of the Command Bar? At the very

least, I would like that color to be less saturated.
