I'm trying to keep my soap as no artificial color so using infused olive oil for my colors. If I'm using multiple colors, what's the best way to split them? Should I divide my total batch by, let's say, 4 and make 4 different batches? Mix all the ingredients except for the infused oils then split that by 4 after weighing the mixed ingredients, then adding the OO to those? I know I'm probably making this harder than it should be but my brain is going back and forth on which is the easiest math part. If I mix first, do I chance mixing a wrong amount of infused oil to the rest of the batch and get wonkiness in the soap?
