Hello all. Is there a color picker tool to quickly change or match one surface material or color to other surface as we have color pickers in different 3d tools?
Eyedropper tool? 
@Japhy any way to it in rhino3d
There are several parts to your question if i understand it correctly.
To match a color you can use the Eyedropper found in the color palette.

To match a surface material or color you can use the Match command/button.
