I don't know anything about the different colors of Cocobolo either, But I can state that the pic does not do the dark colored trumpet justice. I have one and in the sunlight you would be amazed at the deep red and purple color of this wood and the very wild, and wavy grain pattern. I'll also state that it is one of the best sounding and easy to run trumpets I own. Get them while you can at this price. Once word starts spreading I got a feeling the price will not stay where it's at and availability might not be so easy.
