Black walnut.

Red oak and soft maple bark work well. (not on your available list)

20scout was right on with black walnut.

Walnut hulls will give a good dark color but won't hold. There is no effective mordant for walnut so it will fade and wash out. Can you get sumac berries? Using ferrous sulfate as a mordant for a dye made of sumac berries gives a gray that will hold.

Over the years I have used about everything that's out there but for the last 20 or so years I use "Buckbrush" aka: Sumac berries when I want to dye something like traps, cloth, etc. Plus it has a woods smell to it.

Sumac berries , Walnuts

Same here, walnuts or sumac. Both free and common around here.
I wax afterward too. Traps last for decades if you take care of them and don’t let them rust.
Wouldn’t let your hammer rust, should never let a trap rust either.

White oak leaves or boiled Osage bark/wood shavings.

I use hemlock bark on my traps

I bet logwood crystals would create a very dark result.

Tatiana ,that is some beautiful work and colors ! Thank you all for trying to help .I do not have any of the suggestions above here ! Crazy .We do have vine or mountain maple .Should I strip the green bark and boil ? I could just buy the log wood but this type of stuff I am interested in (using available things in nature that are local ). Thanks to all !

Should I get green bark and boil?

Sugarmaple leafs or bark.

Thank you for your help ! I am going to do more internet research on this interesting subject and experiment .
