This image is the result of an attempt to bring colours together by moving pixels, starting from a completely noisy image. A couple of things did not initially go as expected in this attempt: a small number of pixels did not get moved and became isolated, and dark pixels got moved to the borders of the image. Even after some compensation, the effects remain visible: some faint dotting, slightly darker borders and relatively sharper and smaller black specks. Still, these "anomalies" contribute somewhat to give a character of the texture.
