you can copy/paste nodes or the contents of a node... just right-click on title bar, copy... then go to the other object and right-click paste.***(on the shader window background- if bringing in a new node. OR, paste through the title bar on a node if your bringing in only the contents of a node to replace another, like in this case. your root-node) *** i get a bug that delays my pasting. so you might not see the new change take place on the object you pasted until you leave it (pick another object with the color picker) then go back to to the one you changed. it should reload with your changes then) if this is a face-room texture variation/coloration issue, i read it will be addressed in sr3. the fact that the color variations do not at this time carry over any diffuse color values to the figure/body texture !from the face room. also im looking foreward to it, it will help out alot. good luck, hope i helped.
