Or kind of, at least. This is something else I found out by accident awhile back. Blogger has a few different neutral colors, plus a clear option, to match with your blog's design and color scheme.
To edit the Navbar's color, head to the Design tab on your Blogger page. Then, click the edit link (on the blue Navbar menu shown to the right).
And there you'll find the choices. The top blue one is the default and I like that shade of blue, but I tend to go with the black, as it matches many of my designs.
It's just a little thing, but it can sometimes make a big difference in the overall look of your blog.
What color Navbar do you like for your blog?
