You may choose a style using the "Customize" Menu. You have six options to choose from. The entire site was created with the idea that I would only be using the dark blue style. However, I felt like giving the users more options. The only problem is that other sections of the site don't go so well with the light styles. So, if I were you, only use the light styles for reading articles... not so much for the arcade, community, or forum pages - it will look like crap. Enjoy!
