After I draw and research a lot of examples, I found that it's quite hard when the texture come to the darkest one, almost loose its shape and so black. I tried with some help of Photoshop to reverse the colour ( black - white) and found that it's quite interesting. The first 4 column are 2 type of texture, the fifth one reversed in 1 column, the effects quite good, it doesn't seem to loose the texture and the next tone or become another one for me. The last one is a boring one, just one type in one column.
