changing colors in theme

All I want to do is change the colors in the Sante Fe theme. I've downloaded it and tried changing the color codes, but evidently have no idea how to hack a css, which is supposed to be easy. Help!

Sounds like you might need a good CSS tutorial. Here is one that should help:

And a hexcoded color chart:

Another thing that is helpful when editing a style sheet is to figure out which divs and classes correspond to which parts of the page. There are some free Firefox addons that help highlight a page's structure and markup, such as Firebug and the web developer's tool bar.

Or, you can go old school and print out the style sheet and view the source code of particular pages and start matching things up.

Good luck.
