As a little side note - would it be possible to see actual pictures of production units of each colour labelled? This is something most GBs cannot offer and since you have already ran this previously (both R1 as well as R2 in China recently) you could probably pull it off. If you have access to all (or most, as many as you can) the colours that got produced I think it'd play to your advantage to document it as well as you possibly can.
