.one:hover + .two {
    background-color:green;
}

var divOneColor = null;
var divTwoColor = null;
$(document).on('mouseover', 'div', function(e) {
    var clName = $(e.target).attr('class')
if(clName == "one")  {
    divOneColor = $(this).css("background-color");
    divTwoColor = $(this.nextElementSibling).css("background-color");
    $(".two").css("background-color", divOneColor);
    $(".one").css("background-color", divTwoColor);
}
else if (clName=="two"){
    divOneColor = $(this.previousElementSibling).css("background-color");
    divTwoColor = $(this).css("background-color");
    $(".one").css("background-color", divTwoColor);
    $(".two").css("background-color", divOneColor);
}
