  	text-decoration: none;
  	transition: all 0.5s ease;
}

.menu ul li a:hover, .menu ul li a:active {
  	color: rgba(255, 255, 255, 1);
  	text-decoration: none;
  	transition: all 0.5s ease;

Change the "color" property for what you like. Actually it has rgba (red, green, blue, alpha) to make that effect of transparency.
