Hi! How can I change the colour of the shadows?

Hi, everyone, thanks for being such an active and supportive community.
I´am really new to the engine but I have learn so much from the forums.

All I would like to know, In case anyone knows, is… I want to change the colour of the shadows of my scene without colouring the lights.
I was advice I could be done in post production, but don´´t know where to start.
Can anyone point me in the right direction please?

Thanks in advance.

You can try using post process to highlight shadow areas with a color.

You should change the SkyLight colour and build lights
