I recently made the watermelon popsicle soap and fell in love with it so I decided to try to make it with limoncello which is an amazing fragrance oil so I used this yellow dye and it was okay at first and it didn't have as much of pigment as I was expecting but after a week and a half the popsicle soap turned completely Brown it looks like a fudge bar it's not even yellow at all and I wanted this to work out so bad because I was planning on selling it. I'm still hopeful that I can salvage this so if someone can reach out to me and help me figure out what I did wrong or what's I could do differently I would be very appreciative.

This yellow isn't very strong like the other colors. I get a very light color yellow, like beach sand color. Usually the other drops will be more noticeable and sometimes I just use one drop or two and its enough for a pound, but this yellow you'd need way more than recommend if you wanted to get the color you want.
