Can industrial grade mold silicone be adjusted to green and yellow?

When we use industrial-grade silicone molds for flipping and re-molding, the liquid silicone we come into contact with is white or semi-transparent. Recently, many friends have told me that they come into contact with industrial-grade mold glue, which comes in various colors such as yellow, red, and green. How did they make this?
The original adhesive of industrial-grade silicone molds is semi-transparent or milky white. The so-called addition of various colors of mold adhesive is the addition of red, yellow, green, and other color pastes inside the silicone, and then it becomes the desired color.
