I love that green color too! If you haven't already done so, Baqn, and if it isn't too much trouble, could you please post this in the Photo Gallery Forum with details on how you got that color?
Sure I can. I added 15 g Horsetail and 15 g Nettle to 1 kg of oils. I blended the herbs before that so they become into fine powder. Add them when you wish - to oils or after emulsion. In my case there was slight overheating in the mold. I suppose it was from the herbs. I got little cracks only on the surface.
After two weeks the green is changing slightly to brown but it is still intense. I think that it has stopped changing.
