I want to get multi-colored shadows for different objects. To do this, I created 2 light sources and divided them into objects using the “Project” tab. In this case, the shadows are translucent. How can I adjust the scene to get solid shadows?

Uncheck transparency … increase density

Many thanks!. I did not know that Density can be set more than 100%
