This could be an extremely difficult question if your talking in general since people dye their hair all the time (Mine's dyed right now actually) but if you're talking about natural hair color then I believe that would be red hair. I'm not really sure why, it's a matter of genes I guess.
Yellow is said to be the most popular, black in the middle and the rarest color would be chocolate.
The rarest color is bright apple green with flashes of the red, gold and orange fire.
