Change color of assembly

I use the process node to change the color of the assembly product but it did not work. Anybody gives me a suggestion on how to do it?

Try under “Modeling” → “Tools” → “Assign”

Thank for an answer but it is not what I looking for. I want to change color when using “process node”

You can add in process one step and change a color of part.

Otherwise make one additional part in layout and use “ChangeType”
