The reason Facebook is blue because founder Mark Zuckerberg is colorblind. 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 New Yorker. “I can see all of blue.”
The interests he lists on Facebook are bizarre. From Shakira to “ending desire,” the interests Zuckerberg lists on his private Facebook page are certainly unexpected if not plain bizarre. Under interests, he lists the following: “Eliminating Desire, Minimalism, Making Things, Breaking Things, Information flow, Revolutions, Openness.” His favorite musicians include Daft Punk and Lady Gaga.
Another one of the interesting facts about Zuckerberg that he doesn’t seem to care that much about money. One big piece of evidence to support this idea: Zuckerberg hasn’t sold Facebook despite the fact that he’s reportedly been offered at least $1 billion for it.
