Make the most out of your blog, try to make it funnier and more colorful. But I think I will stick to funnier approach to get an attention. Because I believe it's much appealing in such a way that it puts smile on your readers face rather than giving your reader a hard time looking at different colors. One way to give your blog a funnier side is to put comics that shows funny jokes. A user-friendly site that caters to these kind of niche is Blaugh.com. On these site you could even post the sample and free comic on your blog. Like this one.
