During a crazy weekend of paintball, four friends (Brenda, James, Diane, Simon) were having great fun. The paint came in blue, green, yellow and red. Coincidentally, the four friends had T-shirts in those same colors (blue, green, yellow and red) . Brenda used blue paint balls. The person in the green T-shirt used yellow paint balls. James was not wearing a red T-shirt. Diane used green paint balls and wore a blue T-shirt. Simon was the only person who used paint which was the same color as his T-shirt. deductive
