Three shades of gray makes this pattern look like a small carbon fiber surface. Great readability even for small fonts.

Wasn't satisfied with the original's colouring. Too much component transfer and colormatrixes yet the results are lacking a bit. So this time it is a simple black to transparent fade, making it possible remixing easily once there will be other blending modes supported as well. Probably in inkscape 0.92.

Nasty or not, it’s a nice pattern that tiles. Like they all do.
