If you look around at most of the pics of tanks here, it will give you the info you want. Take the pic in your avatar. You see the blue cast that covers most of the picture?? That's controllable by adjusting the white balance. Most point & shoots have a few you can choose from. Might be the same on your phone, I don't know. When you shoot in RAW, the white balance can be adjusted in post. If you're shooting in a jpeg format, you can't. All depends on how accurate you want things.
