I'm sure you have noticed how there is alot of black, white, and red in LOST. I have a theory that every time someone is wearing red clothes or there is red around like in a room, they will have to make a decision. When the red is brighter or there is more red, then it will probably be a bigger decision. Whenever it is less red, but still is close to red like orange or dark red, then it will be a smaller decision. Depending on if the red is next to white or black it would be a good or bad decision. I am not sure how this would fit into the plot, and it is just a theory, but i'm just pointing it out. What do you think?
