Is it possible to make a render in which the coloured shadow of stained glass will be visible on the ground?

If yes, could you give me tips on how to create this? I just made a very simple render of a product made of coloured glass on a stone floor.

I added a spotlight above it but no colour on the ground could be seen.

This is for an art project and I am designing it in SW anyways and was hoping this would be possible.
