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.
Blake used blue paint balls. The person in the green T-shirt used yellow paint balls. Charlie was not wearing a red T-shirt. Drew used green paint balls and wore a blue T-shirt. Alex was the only person who used paint which was the same colour as their T-shirt.
Can you tell which colour paint they each used and the colour of their respective T-shirts?
