During a crazy weekend of paintball, four friends were having great fun. The paint came in blue, green, yellow and red. Coincidentally, the four friends had T-shirts in those same colours. 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 colour as his T-shirt. Can you tell which colour paint they each used and the colour of their respective T-shirts?
