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.

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

I’m guessing this is related to the Sony Vaio? It’s a nice pattern no matter where it’s from.
