For accurate photo editing, Night Light should be off. It shifts your display’s white point, so you’re judging color through a warm screen and will likely over-correct toward blue.

Best practice:

• Disable Night Light for editing.
• Use a calibrated monitor if possible, ideally with a colorimeter.
• Be aware that ambient room light also affects how you perceive color.

Turning Night Light off only briefly may not fully solve it, because your eyes and brain need time to adapt. If your display shift is constant and you must keep it on, one workaround is to use the same temporary adjustment layer while editing so the image appears more neutral to you, then remove that adjustment before saving/exporting. You can also check neutral areas with your editor’s eyedropper/color readout tools.

But the simplest and most reliable answer is: edit under consistent viewing conditions, with Night Light off, and preferably on a calibrated display.
