The Facebook Founder is known for his simplicity seen in a number of psychological advantages to never changing his look.
Years back he said:
"I really want to clear my life to make it so that I have to make as few decisions as possible about anything except how to best serve this community,”
“I'm in this really lucky position, where I get to wake up every day and help serve more than a billion people. And I feel like I'm not doing my job if I spend any of my energy on things that are silly or frivolous about my life.”The choice of gray and blue comes from his colour blindness, which explains why Facebook has a blue thematic colour.
