Shadow color

Hi,
how can I change shadow color? There is example with lighted object:

and on the next picture there is light but intensity is on 0:

All what I need is how change the shadow from grey to black, bc I dont want a grey shadow. The same for spot light when is lighted object and unlighted have black shadow. Many thanks for answer.

Andy.

It’s the “Ambient Light” in the RenderSettings of your project.
