At settings other than K (Choose color temp.), 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.

Highlight a white balance option and press 2 (if a sub-menu is displayed, select the desired option and press 2 again to display fine-tuning options; for information on fine-tuning preset manual white balance, see “Fine-Tuning Preset Manual White Balance”, 0Fine-Tuning Preset White Balance).
Fine-tune white balance.
Use the multi selector to fine-tune white balance. White balance can be fine-tuned on the amber (A)–blue (B) axis in steps of 0.5 and the green (G)–magenta (M) axis in steps of 0.25. The horizontal (amber-blue) axis corresponds to color temperature, while the vertical (green-magenta) axis has the similar effects to the corresponding color compensation (CC) filters. The horizontal axis is ruled in increments equivalent to about 5 mired, the vertical axis in increments of about 0.05 diffuse density units.
D500 setting for auto fine tune. Auto AF Fine-Tuning. The D500 can fine-tune autofocus automatically. The results can be used with all lenses of the same type. Use only as required. AF fine-tuning should be performed at the focus distance at which the lens is normally used; fine-tuning performed at short focus distances may be less effective with distant subjects and vice versa.
Press J to save settings and return to the photo shooting menu. If white balance has been fine-tuned, an asterisk (“U”) will be displayed in the control panel.
Fine-Tuning in Live View
I am sure many of you have gone through with your Auto focus fine tuning process with your new D810. I would like to know your thoughts. AF Lenses I currently own: Nikon 24-70 f2.8, Nikon 85mm 1.4G, Nikon 105mm f2.8, Nikon 300mm F4, Sigma 35mm 1.4 ART (Not yet tuned this one, but this one is having weird metering issues with D810 in the.
To fine-tune white balance during live view, hold the U button while using the multi selector. Press 4 or 2 for Amber–Blue and 1 or 3 for Green–Magenta.
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.
Any given change in color temperature produces a greater difference in color at low color temperatures than it would at higher color temperatures. For example, a change of 1000 K produces a much greater change in color at 3000 K than at 6000 K. Mired, calculated by multiplying the inverse of the color temperature by 10 6, is a measure of color temperature that takes such variation into account, and as such is the unit used in color-temperature compensation filters.
