Answer: Zuckerberg’s Color Blindness

If you look at Facebook’s main page and interface with a discerning eye, you’ll find yourself wondering about the blue-on-blue color scheme. Why so much blue? What prompted Facebook to shade everything from the title bar to the interface buttons in various shades of dark blue, light blue, blue-gray, and all their spectrum siblings?

It wasn’t heavy market research, superstition, or any reason beyond the genetics of Facebook’s founder, Mark Zuckerberg. Zuckerberg is red-green colorblind and when he was designing the fledgling Facebook at Harvard University, long before he was aware he suffered from red-green color blindness, he selected the colors that appeared the richest and most vibrant to him–and the millions of people around the globe who also suffer from red-green color blindness.
