One of the hardest things about making websites look good is getting colour swatches that work.  So, I'm going to start throwing some out there that you can use in your web pages.  These are colors that typically work together, you may need to mute some of them down a bit, or choose lighter versions for backgrounds and such, but it's a great place to start.

#330000 #666633 #663300

#996600 #666666 #663300

EDIT: I've added a colour converter tool to my web site. This will convert colours from their 0-255 range to hex values.
