John,
Nice looking call. Looks like you are getting doing well.
Color wood is made by the same company as dymondwood (Rutland plywood). The differences I have noticed between the two are dymondwood seems to have more vivid colors, is denser and does not require any other finish but a good polish (like acrylic) Dymondwood also cracks easily if you get it too hot when drilling or sanding. The piece you have appears to be the came color that richards microfit (custom gun stock supplier)calls brown laminate, I am not sure what the official name issued by Rutland is though. If you wish more inf regarding this wood, try rutply.com. That is the website for for the company. Hope this helps.
