In the file: html.pl
Add the following near the top (below where the $html_title = 'your site title' is to make it easier to find/update)
$font_red = 'FONT FACE="verdana, arial, helvetica" SIZE="3" COLOR="#FF0000" ';
$font_blue = 'FONT FACE="verdana, arial, helvetica" SIZE="3" COLOR="#0000FF" ';
$font_green = 'FONT FACE="verdana, arial, helvetica" SIZE="3" COLOR="#00FF00" ';
Then use <$font_red>to make something red</font> etc. (which basically inserts all of the 'FONT COLOR="..blah..blah" ' into the < > tags.
The color comes from the number #FF0000 (called a hex or hexadecimal number - notice a pattern in the numbering?). For a better selection of numbers/colors go to http://javascript.internet.com and they have a groovy color wheel javascript that you can save and use to pick that "just so" color. Hope this helps...
Ps: spend $25 on 'Perl for Dummies' ('HTML for Dummies' will help also), you'll be glad you did.
