MarionsQuilts ... I see what you mean as to how each of the OBW hexies are melding together.
The OBW pattern somewhat works that way, with no definition from one to the other.
However, when I look at each on its own, I love the designs that are forming with that fabric.
You could move away from a true OBW, and switch it up,
by bordering each in the black or even the grey.
That way you could see the pattern of each, just as you would if doing a 4PP, or the 8-Kaleido.
Here's one that I did ...
Shabby Chic OBW .... Tout Fini! :)
