A vivid bright apple green American .there is a very flat thin 1 1/8" long base chip that takes out some embossing . otherwise, it is a vvnmt insulator. Note: I am listing this insulator for the Trollie Museium of New York in Kingston, N.Y. to help raise funds to support the museium. If you are interested in this insulator or have questions please contact Glen Moffett @845-691-7391 or email glmoffett@yahoo.com Thanks, Mike Spadafora
