The original Dinky was introduced in 1973. The colors available for that version changed slightly over the years, depending on when it was manufactured.
The Dinky species currently in production were released with the last couple of years (I don't have files on these). These come in a variety of colors and finishes, including the tea rose versions.
So the answer to your original question, "What colors was the dinky released in?" depends on which Dinky generation you are asking about.
Thank you for replying to my comment. I should have been more specific with my question, sorry. I was wondering if it came in Sage or any other green- before the newer ones. I must've been thinking about the Pocket Purse at first.
