I agree color scheme is really bland. Here's an article that might help with that.
Choosing the Right Colors for Your Web Site. Also there appears to be 3 columns in the body of the website. I would consider reducing it to 2 allowing for more content to show on the page at a time. Most people don't scroll down. That being said, I would probably move the blog posts to the top and place the advertisements in the middle. Most times if people think your site is mostly ad related they leave. Hope that helps.
