Ms. Angela teaches 5 classes of art, each with 3 students. She devised a contest where in each class, each person can only use one primary colour and try to paint the best picture possible with that single colour. However, 1 student wanted to win by any means necessary. The student ruined some of the paintings by the other students by splashing it with their own paint. You have to find out who is the saboteur and what colour was the final result of everyone else's paintings. E.g. if a red painting was sabotaged with blue paint, the final result would be purple.
