I have the website EggMoney.com
I am using the NavBar section for the top menu. (About Us, Contact Us, Book Reviews, etc.)
I am using the CrackBar section for the middle menu - just below the Branding Section. (Home, Asset Protection, Business Planning, etc.)
I am using light grey background for both menus, and they both use black as the foreground color for the menu items.
When the menu goes "responsive" - it uses a drop down menu - the NavBar section continues to use BLACK as the foreground color.
However, the CrackBar section changes the foreground color to WHITE which makes it difficult to read on the light grey background.
I tested it with an Apple iPhone 4 using Safari as the browser, and a Samsung Galaxy III S using Chrome and Firefox.
