I made lavender eo soap but didn't add enough lavender color and it turned gray. I thought that if I added some red it would bring out the lavender color. I was wrong, it turned red. So I hurried to my eo shelf and found something that would go with lavender but that wouldn't be too bad with a red color. I added about 1/2 ounce of Tangerine. I didn't weigh it because the soap was tracing fast, I was soaping way too hot. I put a lid over part of the mold, just to keep the towels off of the soap and put it to bed. This morning I unmolded it and the portion that had the lid on it is lavender colored and the rest is kinda reddish/gray. Oh well, we live and learn.
