It may be hard to see the color, but the silk dyed in the indigo I harvested turned a pale aqua. The cottons and the wool didn't absorb much color.
My other wisp of silk blew away in the wind today. It was a darker aqua, perhaps because of the rust in the pot.
I found that the indigo that has been growing in the water was much easier to work with then the indigo that has been in the soil. It breaks down easier, which in turn, allows the color in the leaves to release better.
I have a theory that indigo that is grown in soil and well watered would likely be easier to work with as well. I have been stingy with the water this summer. Something to think about for next year.
