Another fine example of a color variation collage, does seem more striking then even the last one...actually I believe the opportunity for variations of color and shape is endless, great endeavor here Pyrrhula! Nice work!
@tonyjsisti@bruni Sorry , I don`t agree with you. I`ve tried several possibilities within the rules that don`t work .
