They are sharpied
They should be. I’ve seen countless colored rubber bands, sprockets, gears, pieces of metal, polybicarbonate (or whatever it is called), etc.
Was the sharpie used to change the properties of the rubber band? Does the sharpie change the properties of the rubber band? If the answer to both is no, and this is just aesthetic, then you’re fine. I would recommend just buying rubber bands in the color you want rather than coloring them individually.
