How to update color of transformed actor?

I’ve set the color property of the actor to red
but when I transformed the actor by setUserMatrix() the actor always changed into black (the red color disappeared)
For more information, I’ve already instanced scalarVisibility(false) to the mapper of my actor.
Could it be the lighting and camera that I need to update? I have searched for ideas but couldn’t find the solution.
I’ve called the mapper and renderer to be modified after setUserMatrix(). What should I do next?

Any idea would be great. Thank you in advance.
