In life, intricate lights and uneven surfaces of objects reflect each other, making the whole environment illuminated, as if by a layer of light evenly enveloped, this light is generally called Ambient Light. By adjusting the ambient light, is the most direct way to adjust the overall illumination of the environment, but also an effective way to express the atmosphere of the environment.
Select Scene in the Hierarchy panel and set the properties in the ambient component of the Inspector panel.
Note: since the ambient light is directionless, it cannot produce shadows.
