Red is saying that he won't get out of prison until he's old and gray. \nAlso, the term "lost my marbles" refers to ones loss of sanity, so Red is implying that his "marbles", or sanity, will be almost gone before he gets out.\n\nGreat movie, great book.

I was in Iraq, and i think what you are doing is a great idea, but why red?  Red reminds me of blood, and pain.  But I will wear it for my brother's and sisters who are away from home.

The red you are seeing is caused by the blood vessals in you eyes dialating.  Stop smoking pot.  Its not an escape; its a trap.  You can do better with a clear mind.  Believe in yourself.

Before reading the additional details, I would have said:\n\nIn the red refers to a negative balance as far as money.  Therefore Less in the red would refer to getting closer to breaking even.\n\nHowever... I've never heard of the saying you mention.

I have seen many answers to this question so it is not definitive.\n\nSome say it is a distress call from the tree, meaning it is ill or something.\n\nOther say that it a special type of chlorophyl that you can see only after the green color is gone AND there is sunlight for 1-3 days (or some length of time) at the right time.  Then the leaf wil turn red.\n\nI have some 50 trees in my backyard.  None look ill and stressed.   From experience in years that there was very little sunshine almost no red leaves were to be found.  Still looking though.
