If you want to really do all this yourself I recommend learning basic HTML and CSS as a minimum.
first download crimson editor.
http://www.crimsoneditor.com/
Ok once you have it installed, open the CSS file that is controlling the look of your site and search for VertMenuItems.
the code you are looking for will be something like...
A.VertMenuItems:link {
COLOR: #ff0000;
TEXT-DECORATION: none;
font-size:12px;
}
A.VertMenuItems:visited {
COLOR: #ff0000;
TEXT-DECORATION: none;
font-size:12px;
}
A.VertMenuItems:hover {
COLOR: #000000;
TEXT-DECORATION: underline;
font-size:12px;
}
A.VertMenuItems:active {
COLOR: #ff0000;
TEXT-DECORATION: none;
font-size:12px;
}
Change the colors there and you are on your way.
