What are the ingredients in Theraputty besides organopolysiloxanes and specifically what is used to color the putty?

Theraputty typically contains a blend of silicone polymers, fillers, and additives besides organopolysiloxanes. Common ingredients include mineral fillers for texture and stability as well as various plasticizers to enhance flexibility.
