Hi Keith & all > I would think that black wax when "pulled" would be gray/off white a it gets thinner. The colour gets quite dissipated as the wax is re-worked. The coloured wax probably gets diluted with freshly produced wax as well, leaving only a trace of the original coloured wax, in addition, mouthfuls of wax will be taken and used elsewhere. My experiment was with queen cells, but I think the results illustrate the foundation drawing point in the same way.
