The following is a little information you might find interesting. "Color played a significant role in the success of Cambridge Glass Co. They produced opaque glass and then moved onto transparent colors. The opaque shades were produced in early 1920s with colors such as helio, jade, primrose, azurite and ebony. In the latter of the 1920s there was a shift to transparent colors in light colors. In the 1930s, the company moved to darker colors such as forest, amethyst and royal blue. Towards the end of the 1930s, most of the lines made were done in crystal. One of the darker colors they started to use was the amethyst which they invented and patented.
