I've always been fascinated by the color module. If you've ever selected a color palette for the Garland theme, you know how cool this module is. So a couple of weekends ago I decided to buckle down and figure it all out. It wasn't the easiest module to learn, but I have to say it felt really, really good when I finally got it to work. It's not overly complicated, but there are a lot of configurations to keep track of.
I kind of liked my experimental theme, so I started using it for myself and contributed it on drupal.org as Aquanaut.
If you want to get started with the color module, I highly recommend reading this doc page. It covers all of the basics. A couple of things that I learned:
/** Don't use this format **/
a:link,
a:visited {
color: #336699;
}
/** Use this format instead **/
a:link, a:visited {
color: #336699
}
Happy theming!
