I like the different dye lots from the dark blue trousers and sack coat. Over the course of 10 or 15 events, one of my file mates and I had a running game of "how many shades of blue can you spot in the column?" Generally, we could identify at least 7 different shades of blue (although blue is a relative term from purple to faded black) for sack coats, 20 or more different shades of sky blue trousers and three or four different dark blue trousers (In the Regulars, we wear dark blue trousers more than most.)
Forage caps is where it really gets interesting. Marshall and I once counted three forage caps which were the same hue in a formation of three or four companies while we were waiting to move into position at Cedar Creek a few years back. That is about 200 different shades of dark blue. In bright sunlight, you can really see the differences.
Lots of variables on the consistency front; what dye was used, what is the wool content and what manner of weave is there in the cloth, how old is the garment, how much exposure to sun and weather, are the items washed or dry cleaned etc.
Looking good Bud, keep up the good work.
