I usually don’t plan ahead with the possibilities of color discoloration on my soaps. There are soapers that use it to their advantage and usually plan on the fragrance discoloration to work with their design. I just go with it. I find it interesting to see how a fragrance can play with your pre-selected colors. Having said that, I do tend to stay away from most of the sweet and sugary fragrances. I think I have only soaped with Vanilla Fragrance oil once, and I purposely made my soap bars brown.
I did once have a soap batch that turned out very nice out of the mold and as soon as it started to cure it turn a dirty looking beige. It was pretty weird and kind of fascinating at the same time.
So I was wondering if I should do any type of planning when I decided to soap with my next fragrance: Dreamcatcher (from Rustic Escentuals). Its a nice light, feminine fragrance. The vendor does warn about slight discoloration so I thought to add a little more Titanium Dioxide to see if it will lighten it up, and decided to add some yellow, and red mica.
I was surprised to see that it discolored, but not dark, instead yellow. At one point my yellow and white were just about the same color but eventually the yellow started to pop a little more.
