Shadows are not always black!
Shadows are absolutely fascinating to play around with.
In this Exploratorium demonstration you can see that a black shadow is only a subset of shadows that can be formed on the screen.

If you have multiple sources of light with different colors, then you can additively combine colors to get shadows of various shades.

In this case where you have multiple sources of light, only when the object blocks off light from all three colored light sources do you get a black shadow.
Since we do not deal with multiple colored sources of light on a daily basis, go ahead, give this simple experiment a try. It’s totally worth it!
Have a good one!
