Have you ever thought why everything in Facebook is Themed blue ?
I guess not. Then only reason for this is that Mark Zuckerberg is red-green color blind. Surprised but its true. In the interview,he told reporter Jose Antonio Vargas that “blue is the richest color for me — I can see all of blue.” you can also easily guess this if you see these pictures .everything is blue from logo to log-in.
