Make your own. Everything else I think you can purchase is going to be glimmery. Although I don't know whether it's acid free, I use water mixed with food coloring. Or acrylic paint mixed with water - I would try plain red with a tiny drop of black to make it dark.

You could use Distress re-inkers... Just a thought. I know that the Fired Brick ink pad can look a little bloody. I tried to use some on white flowers on a Christmas project, and it looked gross- very much like blood.
