white balance
In short and in plain language
White balance is a setting on the camera.
It adjusts the colours to the light. If it is wrong, a picture may look too yellow or too blue.
A grey card in the picture helps to set it right later.
Definition
White balance is a camera or smartphone setting that adjusts colours to the available light. If it is set incorrectly, images look too yellow or too blue, for example. A grey card in the shot can help to set it precisely later.
