In your .css file, assign these-

.Login {
    font-weight: bold;
    font-size: 8.5pt;
    color: #003366;
    font-family: Arial, Helvetica;
    text-decoration: none;
}
A.Login:link {
    text-decoration: none;
    color:#FF9900;
}
A.Login:visited  {
    text-decoration: none;
    color:#eeeeee;
}
A.Login:active   {
    text-decoration: none;
    color:#eeeeee;
}
A.Login:hover    {
    text-decoration: none;
    color:#cccccc;
}
.BreadCrumb {
    font-weight: bold;
    font-size: 9pt;
    color: white;
    font-family: Tahoma, Arial, Helvetica;
    text-decoration: none;
}
A.BreadCrumb:link {
    text-decoration: none;
    color:white;
}

A.BreadCrumb:visited  {
    text-decoration: none;
    color:#eeeeee;
}

A.BreadCrumb:active   {
    text-decoration: none;
    color:#eeeeee;
}

A.BreadCrumb:hover    {
    text-decoration: none;
    color:#cccccc;
}

And in the .xml file, set them like this -

<Object>
    <Token>[LOGIN]</Token>
       <Settings>
           <Setting>
               <Name>CssClass</Name>
               <Value>BlueSkinObjects</Value>
           </Setting>
       </Settings>
</Object>
<Object>
    <Token>[BREADCRUMB]</Token>
       <Settings>
           <Setting>
               <Name>CssClass</Name>
               <Value>BreadCrumb</Value>
           </Setting>
           <Setting>
               <Name>RootLevel</Name>
               <Value>0</Value>
           </Setting>   
       </Settings>
</Object>

Hope this helps.
