why the origin of the facebook page is blue?

Know why the origin of the facebook page is blue? because the founder of Facebook, Mark Zuckerberg was color blind. That is causing a page full of blue Facebook.com and never changed until recently.

Mark Recognition is published by The New Yorker magazine and quoted by CNN.com. Mark has a red-green color blindness.

"This is what I saw was blue," he admits in the magazine.
