I have a layer (LAYER1) with an object (I will call LEAF1), and clones of LEAF1 created with the Spray

I want a duplicate layer (LAYER2) which includes a new leaf 'master' object (i will call LEAF2) and the clones from Layer>Duplicate
I want to then change the color/fill of LEAF2 so the LEAF2 clones in LAYER2 change.
That was my thought process. After I use Layer>Duplicate I can find no way to set the LAYER2 clones to inherit color/fill from the new LEAF2 master object. I looked at Object Properties thinking I could point the clones to LEAF2 but did not figure out how to do that.
Is there a solution?
thanks
