Well, depending on the plastic, you could get either. If they use a
concentrate (for color), and a blank type of plastic, then they would just
need to change the concentrate feeder. If they use pre-colored plastic, then
they would need to clean both the hopper, the concentrate, and the injection
mold machine as well. To get uniform color, you usually get the pre colored
stuff, which is more expensive but better in terms of running production
smoothly.

got to mix the plastic and everything. Fun!)
