What is the purpose of adjusting the white balance to 1000-4000K?

Adjusting the white balance to a range of 1000-4000K primarily serves to cool down warm light, which typically includes orange and yellow hues. This setting is often associated with lighting conditions such as incandescent bulbs or sunset, where the light tends to be warmer. By setting the white balance to this range, photographers can neutralize those warm tones, resulting in a more accurate representation of colors as they would appear under natural daylight.

This adjustment is crucial because it helps maintain color fidelity and can significantly affect the mood and atmosphere of the photograph. When the white balance is correctly set, what should appear as white in the scene will actually appear white in the photograph, preventing the overall image from taking on an unwanted color cast.
