White balance (WB) is for making the white areas look white. Normally, 
the <Q> (Auto) setting will obtain the correct white balance. If natural-
looking colors cannot be obtained with <Q>, you can select the white 
balance to match the light source or set it manually by shooting a white 
object. In Basic Zone modes, <Q> will be set automatically.
