Time to enjoy some colours
During a vacation, the Tan family was at an overseas chemistry laboratory. The chemist was demonstrating to them how an exotic chemical is made. He showed them the following graph:
Mr Tan could work out what colour the chemical was without looking. He realised that it was one of his children's favourite colour and asked whether a sample of that chemical can be kept as a souvenir. Mr Tan was thinking of...

The favourite colours of his children are as follows:
Benedict - green
Bob - blue
Brenda - red
Brian - orange
Billy - yellow
