If you want to change the middle grey colour, in the CSS look for the following block of code:

.sidebar-nav li {
    text-decoration: none;
    color: #fff;
    background: rgba(255,255,255,0.2);
}

then change the background line to whatever colour you want using that syntax or using the normal syntax:

background-color: #F5F5F5;
