Only the thick "sashiko" threads are mud dyed (dorozome). Same as the 123 those are the only natural indigo threads in the fabric. Honestly, the mud dyed ones are more authentically dyed than the 123s. Figure the guy at Kanaikougei (the mud dyer) has to climb in a pool of muddy water for every hank of yarn. Whereas, the 123s are dyed in a massive indigo dyeing factory in Hiroshima, a process that is a partially automated rope dyeing facility.
The mud dyeing process is actually not all that muddy as the name suggests. Its primary dye agent is from bark and wood of the Rhaphiolepis umbellata plant. The mud part is unique to Amami Oshima island, the iron-rich content of the soil acts as an iron mordant which darkens the brown to a very dark brown. Here is the dorozome color on the traditional silk kimono of Amami island, called Oshima-tsumugi. I have had a few pieces dyed there over the years we even experimented with dyeing a vintage nylon MA-1 in doro black with great success. Too bad it shrunk a size... Not sure if this will alter anyones thought on the century denim but I hope at least it gives a bit more insight into what goes into making a product the hard way.
