Change sticky menu color and put the footer into full screen

How do I change the sticky menu color?

Currently it is grey. I want it to be black. I will attach my index below.

Also how do I do so that Footer are inside the full screen? Now the video and header is fullscreen but we have to scroll down to see the footer.
I want my footer to also be inside the fullscreen. How do I do that?
