Hilde, I do have a black background, not a rich super black.
I thought about painting, but I'm horrible with paint.
Hornwort has to be trained to root. It takes time. You could try tying it with thread to a rock.
If you used silk it would be shiny and darker.
I painted a tank and regretted doing it. It is a pain to remove.
You need to research plants that are suited for your tank. Then posted in the for sale section. You will get more for your buck from a member.
