I used to have a list of all the different colors of bakelite, or at least what people commonly call the colors. Examples are pea soup, tomato soup, butterscotch, egg yolk, Mississippi Mud. I will post photos with examples as I run across them.
The bangle shown in this post is a good example of Mississippi Mud bakelite. It will normally be a deeper brown color with lighter color browns swirled through the body of the bakelite.
