The author presented the outcome of research relating to red organic dyes applied in table painting from Gdańsk during the second half of the fifteenth century. The investigations were based on fluid chromatography HPLC combined with UV-VIS spectrometry. The results of the research demonstrated the use of a dye obtained from a plant from the Rubiaceae family, which in the majority of cases was madder (German: Krapp, Rubia tinctorium L.). Previous studies showed that the same plant was simultaneously employed for Polish table painting in Silesia. This particular type of dye brings the Gdańsk variety closer to the range of North-European tradition.
