New Template

Well, I decided to change the look of my blog. It looked a little dark before. Since my writing can sometimes be a bit dark on it's own, I thought I should lighten it up a bit. I have become fascinated by the HTML that sets the template up. How can I change this? Personalize it a bit. I don't know, so I will buy a book about it. Any good reason to buy a book, right? Maybe that's just me.
