Color!

I have been moved by idea of minimal component. If a component does not add anything to the whole, why bother to use such a component. Well why the same idea cannot be applicable to photography? I am sure it does. If color is not relevant to a photograph, why bother to compose in color? If subject is the only thing that matters in a photograph, why bother to compose in color? Don't get me wrong, some composition can be made of color, I am not talking about those composition.

Well, in this photograph all that matter is the girl and her emotions, why bother to use color! Is not it neater in black and white?
