White

In most Western countries white is the color for brides. In the East, it's the color for mourning and funerals. White is often associated with hospitals, especially doctors, nurses, and dentists. Some cultures viewed white as the color of royalty or of dieties. Angels are typically depicted as wearing white. In early Westerns the good guy wore white while the bad guy wore black.

White is the color that represents purity, neutrality, sterility and youth. White is often associated with cleanliness or sterility. White is also associated with neutrality and peace — hence a white flag for surrender or parley. For the same reason it is a neutral color that will continue to be the preferred backdrop on websites and the "color" behind the color. In Western tradition the bride wears white, a custom dating back to Ancient Greece. There, the temple that was dedicated to the goddess Athena was made of white marble. It led to the linking of the color to virginity
