In Life of Pi, the colour orange is repeatedly used to aid in Pi's survival. Symbols: Survival Safety Sanity Home Training
The cookies show how Pi's journey on the Pacific Ocean changed him. Symbols: Carelessness Wastefulness The true value of what we have Do not take things for granted
Throughout the novel, Pi uses the orange whistle to train Richard Parker. Without the whistle, Pi would not have been able to tame Richard Parker and most likely would have been killed.Richard Parker himself, who aids the most in Pi's survival by keeping him sane, is orange. Funally, the life jackets and oars foud on the lifeboat are also orange.
Pi, once in the hospital, hoards the cookies that he is given. While on the Pacfic, Pi learned that everything that he has can be taken away from him, so he hides the cookies so that they will not have that fate. The value that Pi sees in a cookie shows that we are careless and wasteful, and do not think of how much we take for granted.
