This tiled background comes in red and consists of tiles that look like gemstones. It is more for blogs or social profiles, I think.

More bright luxury. This is a bit larger than fancy deboss, and with a bit more noise.

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.
