Facebook's brand color was influenced by Mark Zuckerberg being color blind

According to the New Yorker, Mark Zuckerberg - the billionaire creator of Facebook - is red-green colorblind. This means that the color that he sees the best is blue. This fact played a major role in the decision on what color Facebook’s logo should be. Zuckerberg ended up selecting the color as it is the richest color for him, which means he can see the full spectrum of blue. It seems like the decision paid off since the Facebook logo is one of the most well-recognized logos in the world.
