Fine-Tuning White Balance White balance can be "fine tuned" to compensate for variations in the color of the light source or to introduce a deliberate color cast into an image.

Use the multi selector to fine-tune white balance. White balance can be fine tuned on the amber (A)-blue (B) axis and the green (G)- magenta (M) axis. The horizontal (amber-blue) axis corresponds to color temperature, with Coordinates each increment equivalent to about 5 mired. Adjustment The vertical (green-magenta) axis has the similar effects to the corresponding color compensation (CC) filters. Increase green Green (G) Blue (B) Amber (A) Increase magenta Increase blue Magenta (M) Increase amber A White Balance Fine Tuning The colors on the fine-tuning axes are relative, not absolute. For example, moving the cursor to B (blue) when a "warm" setting such as J (incandescent) is selected for white balance will make photographs slightly "colder" but will not actually make them blue. 97
