As a note, we can do this in QGIS using the Topological colouring.

Hi @ejmt​ 

 

You can use the transformer SpatialFilter to do a spatial relator beetween the geometries. After you can use the transformer TestFilter to isolate the colors that you want by fme_color or another attribute of color that you have.

 

 

Thanks in Advance,

Danilo
