Applies textures (Voronoi textures) randomly to the color areas: no sophisticated research into applying the best texture with color or lume; it's a little filter.
Therefore, the results are sometimes good and sometimes worse (depending on the texture selected by the filter for each area).
Give it a try if you like.
The attachment also includes (~17 MB) a starting set of 55 patterns (png) "Voronoi_Diego" + 32 patterns (jpg) "Voronoi_Issa"; as usual, you can add/remove whatever you want.
Lots of examples here.
