We've all done it, taken a picture indoors and it's come out orange because of the artificial light because the camera has got confused, it finds it very hard to lock in the right colours like our brains do.
Confusingly White Balance has very little to do with actual white and more to do with how the three primary colours Red, Green and Blue are recognised.
The best way to fix this is to shoot in RaW rather than jpeg but some cameras don't have that option...
Many though do have a way of selecting a white balance in camera. The tungsten setting for example will vary the colours and lessen, or even eliminate, the orange cast, the flash option will register light as bringing a sharper white cast to things etc...
Especially if shooting indoors this can be a photo-saver, jpegs are a right sod to correctly edit to fix colour casts and by simply using the tungsten or artificial light setting you can get a far more natural looking picture straight from the camera.
Remember, if there's any questions or a specific camera subject you want me to cover, just ask
