The building at 508 Warren Street deserves attention for the beautifully preserved squares of colored glass along the base of its display windows.
The colored panes were not merely decorative. In the 19th century, artists' supplies were sold in this shop. Some of the Hudson River School painters bought their supplies here. The story goes that the panes of colored glass were used to judge the purity of paint colors. Since the colors in the stained glass remained constant, a level of consistency in the colors of hand-mixed and hand-prepared oils could be achieved by comparing them with the colors of the stained glass.
