That is a useful chart

Can you confirm what background color they were using?
Their graphics version (the one with brown outline) looked like it had SC3311, which is pretty close to the original target. If the color could be picked from thread colors, I think 276 would be closest.
I am just guessing that the sample now has either "Olive drab" or SC351 as background... or then the photo might just give such impression.
IMHO, SC3311 or a bit more colorful SC336 might best follow the assigned colors.
But, in any case, I'll trust your opinion, since you can see the sample in real
