If there is not a blue object reflecting in the silver then the problem might be with the camera. Selecting a preset white balance should sort out the problem in most circumstances and should certainly correct for daylight (as opposed to sun light). Some cameras have a custom white balance which is often more accurate than the presets. There are still some other possibilities. Try including a neutral grey card (a common photographic accessory used to check white balance and exposure) in one of your shots. When you sample the colour of the grey card in your editing software, the red, green and blue values should be the same (plus or minus two). If there is a white balance problem, one of the red, green or blue values will be significantly different from the others. If the white balance is correct and the card still appears to have a colour tint on screen, it will be because your monitor needs calibrating and profiling. If you try to correct any colour cast by eye without a profiled monitor you could end up introducing colour errors. The bottom line is that you need to do some test shots in your chosen lighting conditions with a grey card or better still a colour checker card. I’ll be dealing with this in the workshop on 29th January if you can make it.
