@pixelandmore You can use the custom css for this. In the dashboard, go to Appearance->Theme Options->Design Options Tab->Custom CSS. Paste the following css and click on ‘Save all Changes’.
#access a {
color: #F6FF00;
}
#access ul li ul li a, #access ul li.current-menu-item ul li a, #access ul li ul li.current-menu-item a, #access ul li.current_page_ancestor ul li a, #access ul li.current-menu-ancestor ul li a, #access ul li.current_page_item ul li a {
color: #00FF3C;
}
The first one is for the menu color and second part is for the dropdown menu color. You can change the color code to your liking. You can look for the color codes in this link http://www.colorpicker.com/.
