In our graph, we have some common labels (e.g. "CAR") and then we use combinations of those labels so we might have nodes with labels ":CAR:SEDAN", ":CAR:SPORTS", and ":CAR:AWD". In the graph visualization UI, if I try to add custom colors to labels, SEDAN, SPORTS, or AWD, it has no effect. all nodes are the same color as what is inherited by label "CAR"
