Why Facebook is Blue – Colourblindness of Mark ZuckerbergJune 25, 2018
According to The New Yorker, Zuckerberg is red-green colorblind, which means the color he can see best is blue. That also happens to be the color that dominates the Facebook website and mobile app.
“Blue is the richest color for me,” he told the magazine. “I can see all of blue.”
Another important commercial factor for using blue color is the fact that most colors tend to distract the viewers. Blue on the other hand acts as a transparent background to the main content as visible to the human brain due to which most popular websites tend to use the blue color. It can easily be called a webmaster’s favorite color. Blue color is also sometimes referred to as ‘Nirvana’ for the brain.
All these factors make blue a prominent color on Facebook.
