Working with Acraglas Gel , looking for a very dark brown dye . Any ideas out there ?
Happy New Year and all the best in 2020

I just mixed a little bit of the black with the brown to darken up their brown dye. Worked ok for what I needed but may not give you the shade of brown that you are after. I have also used hobby paint sold at walmart before.

Brownells carries both brown and black.

You grind up some of the dark wood that you are trying to match. Sawdust. Mix it with the Acraglas with some of the brown dye that comes with it. Repeat that until you get the color you want.
Do not use oily wood. Probably, don't.
