Next time you’re on Facebook (which is probably now…) take a look around at the aesthetics of the site. What color do you notice as being the dominant color? Your first response should be blue. That’s right, blue is the dominant color of Facebook and that is not by accident. According to an article I just read by USAToday, blue is the dominant color on Facebook because Marck Zuckerberg (Facebook’s founder and CEO) is red-green colorblind.
