When you open Facebook, everywhere from its login page to Facebook groups to practically any section, you will see only blue. Ever wondered why is Facebook so blue in colour and not changing its colour scheme?



Ever since they started as 'thefacebook', Facebook has stayed with the blue colour theme. Although major changes have been made to the Facebook theme since its launch, the major unchanged thing has always been its blue colour.

The reason is actually very simple… Mark Zuckerberg, the young founder of Facebook is red-green color-blind and blue is the richest colour for him.

According to The New Yorker, Zuckerberg is red-green colourblind, which means the colour he can see best is blue. That also happens to be the colour that dominates the Facebook website and mobile app. "Blue is the richest colour for me," he told the magazine

Another important commercial factor for using blue colour is the fact that most colours tend to distract the viewers. Blue on the other hand, acts as a transparent background to the main content; almost invisible to the human brain, which is why most popular websites tend to use the colour blue. It can easily be called a webmaster's favorite colour. Blue is also sometimes referred to as 'Nirvana' for the brain.

All these factors make blue a prominent colour on Facebook.

Interesting, isn’t it?
