Your CSS file will determine your colours of your text, so lets start with that.
Lets start with the colour of your links, just to keep it simple.
a:link, a:visited {
color: #000000;
text-decoration: none;
}
That will display all your links as black. So if you want your link to be a different colour, then change the #000000
Now just the general text colour
td,p,div {
font-family: Verdana, Tahoma, Sans-Serif;
font-size: 10px;
color: #FF0000;
}
That will determine that your text on that page will be black, once again, change it to your needs. Also note that you can change the font-size aswell. From that you can find other things in CSS just by trying to find a site CSS.CSS file (normally
www.domain.com/css.css or
www.domain.com/style.css)
