Actually i figured it out, the hover color change is in
.sf-menu li:hover,
.sf-menu li.sfHover {
background: #3366FF; /* only transition out, not in */
-webkit-transition: none;
transition: none;
and the selected color change is in
.current_page_item a,
.current-menu-parent a,
.current-post-parent a,
.current-post-ancestor a,
.current-menu-ancestor a,
.current-menu-item a {
background: #3366FF;
The color code will be different since i already changed the jex code before i pasted them here.
