Once three friends, Mr. Green, Mr. Red and Mr. Blue were having a drink.
One man was wearing a red suit; one a green and the other a blue suit.
"Have you noticed, " said the man in the blue suit, "that although our suits have colours corresponding to our names, not one of us is wearing a suit that matches our own names? "
Mr. Red looked at the other two and said, "You're absolutely correct. "
What colour suit is each man wearing?
