Colored slate surfaces

[CharliesElements]

Hello!!!Fellow Turkey hunters. 
My partner and I are in the works of a new adventure and will be mining colored slate for turkey calls.
We will have several color options to choose from but we will only offer colored slate in 3 1/2 to keep it simple for us while we are starting up.  We aren't up and running yet but should be open to public in a couple months hopefully without any hiccups.
Definitely before next turkey season. 
Trying to get a feel for what colors are your favorites. 
We have a few red and greens now but going to wait til we get these last few business details squared away.  Main colors will be Red, unfading green, mottled purple, purple, black. There will be others but they are very rare and will be limited runs. 
If you would like to send a message to get your name in the loop to be the first to contact when we open the flood gates, your more than welcome.  Have a wonderful turkey season.  God bless
