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.
<Q> is automatically set in the <
A> mode.

To the human eye, a white object looks white regardless of the type of lighting. 
With a digital camera, the color temperature is adjusted with software to make 
the white areas look white. This adjustment serves as the basis for the color 
correction. The result is natural-looking colors in the pictures.
