Relationship between color temperature of light source and photography

The calculation of the color of the optical signal captured by the digital sensor depends on the color temperature. If you want to restore the true color, you must know the color temperature at that time, which is why photography should try to avoid stray light. The temperature on one side of the light is 5000, on the other side is 3500 and there is another 6000. Under such conditions, it is impossible to restore color in one step, so the photographic works that need to restore color should try to avoid stray light, which is also the most important thing in product photography.
