Which theme are you using?
On average the link colors can be changed here in index.css:
a:link, a:visited {
color: #FFFFFF;
text-decoration: none;
}Depending on the theme there may be other areas that need changing as well.
Board name colors are normally under something like this:
.table_list tbody.content td.info a.subject {
color: #FFFFFF;
font-size: 110%;
font-weight: bold;
}Category text/link colors are normally under something like this:
h3.catbg a:link, h3.catbg a:visited, h4.catbg a:link, h4.catbg a:visited, h3.catbg, .table_list tbody.header td, .table_list tbody.header td a {
color: #FFFFFF;
}Chane the #FFFFFF to the color of your choice.
