Review (4/5): Work pretty well
Purchased these for my daughter. She has dark Brown hair that's can pass for black.
We tested all the colors on one patch of hair and the one that dis the best was good. As a matter of fact good was the main one you could see the following day.
Washed out easy with shampoo, no smears on the pillow case and because it was a patch on the top of her head I do not know about it smearing on clothing.
Satisfied over all!
