Background color

I managed to change the colour of the links but I am struggling with changing the background colour of the antimatter theme. I just need it to be some nuances darker. Any idea how this could be done. Very likely I am missing something.

I use sass to compile the css and do not use one of the skeletons.

adding background in _core.scss worked for me.

// Global body styling
#body {
	@extend .default-animation;
	@extend .padding-horiz;
	
	background: $page-bg;
	padding-top: $header-height + $padding-vert;
	padding-bottom: $footer-height + $padding-vert + 2rem;
}
