font colour

I am using the Newsflash theme. As you can see in the css code below, the link colour is set to a dark blue. I want to separate it out so that the links stay this colour, but I want to add something so that the links in the menu items are white instead. I have tried changing the code attached here in part two to set a font color but it doesn't like it. It picks up the font colour from the link attribute instead. How can I change this please?

PART ONE

a:link,
a:visited,
a:hover,
.title, .title a,
.submitted,
.links,
.node .taxonomy,
#aggregator .news-item .categories, #aggregator .source, #aggregator .age,
#forum td .name,
div.admin-panel .description {
color: #000040;
}

PART TWO

ul.menu li {
background-color: #797878;
border-top: #FFFFFF 2px solid;
padding-left: 15px;
margin: 0 0 0 0.5em; /* LTR */
color:red;
}
