I have had a look in the CSS file, and cannot find much, there is a reference to
PHP Code:
.post h2 a{color: #6348411;}
on line 319. You could add your own commands in the CSS though, if you are wanting. Below is how they would look, just replacing the XXXXXX with what colours you want.
PHP Code:
.post a {color: #xxxxxx; font-weight: bold; text-decoration: none;}
.post a:link {color: #xxxxxx;font-weight: bold;text-decoration: none;}
.post a:hover{text-decoration: none; color: #xxxxxx;}
.post a:active {text-decoration: none; color: #xxxxxx;}
Hope it is a bit of help.
