Hello
I don’t understand your question. If it is a question of coloring a “Map”, just use Map colouring Theory. I made a small script for that. You specify the number of color, and the algorithm try. The only tricky part could be the frontier check, but it seems to work here.

Four Color Theorem in Grasshopper

Hello, it was not a so simple problem but it was interesting. I struggle a bit but here is a solution (I hope ).
