Ken Aston was a famous English football referee. He changed how the game is played today. He wanted rules to be easy for everyone to see. He helped players and fans understand decisions quickly. Many people know his name because of his clever ideas. He was a teacher and a soldier too.

Aston made several big changes to the referee uniform. Before him, referees wore tweed jackets and golf knickers. He found a black flight jacket in a surplus store. He liked that it had many useful pockets. He paired it with a white shirt and black knickers. This created the black uniform with white trim used today.

He also solved problems caused by bad weather. One foggy day in London, he could not see the linesman's flags. The flags were beige and chocolate colors. He went to a store and bought red and yellow rain slickers. He made bright flags from these colors. Now, linesmen use bright yellow and red flags.

His most famous invention was the yellow and red card system. He thought about traffic lights while driving one evening. He realized colors could help people understand rules without speaking. His wife, Hilda, cut colored paper to fit his pockets. The yellow card is a warning for a player. The red card means a player must leave the game. This system started in the 1970 World Cup.

Aston worked with FIFA for many years. He helped manage referees for the 1966, 1970, and 1974 World Cups. He introduced boards to show substitute numbers to players. He also started the practice of using a substitute referee. Later, he moved to the United States to teach. He served as a chief instructor for the American Youth Soccer Organization.
