Thanks, Ron. I would say you have the same three colors as I showed.

I know that color differences on cheap chips are always a subjective matter. There might be a range of colors as they fade, for example. However, I think there were reorders of this chip, and so far, I would vote for three different colors. I don't think the reflectivity of the hot-stamp is significant as that can vary easily with process changes in temperature and pressure.
