Mike, The leather in the body of the hood can easily be changed. The rawhide color has been left unchanged except for the brown feathers on it. It could just as easily be a black leather with a black feather.
Dying the rawhide would defeat the purpose. It wouldn't look like rawhide anymore. However we might look at using a rawhhide with a more amber color to it. This would be better for hunting.
We have a split finger tab on our website, but it doesn't have the palm pad or O ring features. We can make that tab with cordovan or "slink" material at that price.
We are considering making the split finger tab with the palm pad and O ring features but I'm still working out the dimensions.
