Red has always been symbolic of blood and life. The universal color of blood binds us all together, giving us a common point of empathy for anyone that’s hurting.

Perhaps because of that connection to pain, the color red is also used as a warning. As the most intense and easily seen color, our eyes and minds quickly become trained to understand that red means STOP—making us think before proceeding.
