Hi, I'm curious if I use a fragrance that I'm aware turns the soap a tan colour if the discolouration will bleed through to the top of my soap batter if I left the top unfragranced. I'm wanting to use coconut cream as the base of my soap which I'm gonna let turn tan as the colour but I want to have a white cream like top. If I don't add fragrance to my white soap will it still turn tan because of the fragrance underneath. Also I have no TD and I'm gonna colour my white soap batter with white pearl mica, I haven't used it yet and I'm wondering if it will colour the soap white or just a lighter shade. Does it colour white as good as TD. Thanks!
