According to a survey conducted by YouGov in 10 different countries, the most popular color in the world is blue. Not only does this survey confirm it, but any other survey conducted for the most popular color also consistently reveals blue as the top choice. For example, in the USA, 40% of men said blue is their favorite color, while only 24% of women chose blue as their favorite. Does it make sense now why Facebook’s interface is blue? The other popular colors in the world are green, red, purple, and yellow. If you don’t like any of the above colors, it is totally normal.
