   > I'm not sure but will it be too complicated on design if we can have different colorBy on each node. Will it be much simpler and less confusing with the itemStyle.color if we only support colorBy on levels
   
   @pissang At present, treemap `colorMappingBy` can be set on node/levels/series.
   I'm not sure how many users user actually set `colorMappingBy` on node, but theoretically it works fine and not difficult in implementation when it represents "how to arrange the color of children".
   
   But if changing the meaning "how to arrange the color of the node self", I have not found an easy way to implement it yet, even though only support it on `levels`.
