Global survey - Black or Color Suits on the Academy Awards, Music Awards and other formal events

Black tie is a dress code of formal wear for evening events and social functions, derived from British and American costume conventions of the 19th century. Do you agree that those old costume conventions should change? Wouldn't it be much better if men dress in colours like women and not wear only black suits on formal ceremonies (the Academy Awards, Grammy Awards, MTV Awards, etc.)? Some men do it, but they are still few.
