BFC0521 Window - Deep Woods Thread Kit

I have a friend that had purchased the Deep Woods design and the thread kit. When she got it we were trying to match the colors from the old threads, that are what are in the file, to the new ones. It is very hard to match as some of the colors are not matching what it says on the new chart and what was in the kit. Is there a way to know what was substituted for what without going through a lot of guessing?
We were hoping to have this project done last week as it is a housewarming gift and now it is on hold. What we ran into was some of the numbers that were on the conversion chart as the comparisons for the old colors were not even in the kit.

Thank you
