Hide, Remove or Color Change the Navbar in Blogspot

Have you ever wanted to remove the default Navigation Bar (Navbar) at the top of your Blogger blogspot which features the search box and other useful links? I myself had wanted to often times, but nonetheless, the ease of signing in and out of Blogger or to access the admin pages of my blog so easily via the Navbar far exceeds my distaste of its previously default blue color.

Great that Blogger has made available for us to alter or change the colour of the Navbar to blend with our blog's theme or design which is a significant improvement aesthetically, especially with the transparency options. Once done, I was most contented and had no desire whatsoever to hide or remove the Navbar ....or so I thought until I learned something new recently!
