If you want to make them completely different than the others, you would go to additional.css and add

#sidebar_container li a
{
color: /*Add your normal color HEX or RGB value here*/
}

#sidebar_container li a:hover
{
color: /*Add your hover color value here*/
}

I tried the additional.css, but it changed the color in other areas instead of just the buttons in the New Groups sidebar area.
