So I was working on a concept soap this weekend and ideally, I wanted it to be a sort of celadon green. The only green botanical I have in hand at the moment is comfrey leaves (note: leaf bits, not powder!), so I infused some OO with the leaves, ended up with a strongly green oil, and figured I'd be good to go for a first experiment.
Using the greened oil as 15% of total oils netted me... something that wasn't green at all!

This soap also has gold mica swirled through it, which contributes to the yellow, but even before the swirl, the base soap was this sort of yellowy color:

I really need to get a picture of my green infused oil for comparison, but I'll say it's a slightly yellower green than lime jello and a bit more transparent.

Possible interference factors:
- there is a tablespoon of honey in this batch.
- there is goat milk powder added to the solid oils; I noticed that this did make the solids rather yellow. (I'm pondering using coconut milk instead to keep things whiter...)
So uh, with all that on the table, my question is, are there natural colorants I can use to get the green color I want with the above ingredients included? Do I just need to up the percentage of comfrey oil I was using? Would some other plant make for a brighter color?
I think clay might provide the color I want, but I don't know if I want the other clay benefits in this particular soap...
Or am I just best off using an oxide or mica here?
Thanks in advance!
