Good morning, I experimented with Indigo Powder for the 1st time yesterday in my cold process swirl soap. My indigo powder is a very mossy, earthy green. I kind of thought maybe it would change to a blueish color as the soap hardened, but this morning it is still quite green. Anyone experience this before? Any tips or tricks I should know? I don't mind the way my soap loaf turned out, but it just wasn't what I was expecting!
