i have only made pb and j once, and i had to mix many many colors to get the purple i wanted, i have since added a ton of colorants so i will have to decide which purple i want to use for it, probably lureworks purple with a few drops of either black grape or x2 junebug to darken it up. the peanut butter side i liked was x2 pumpkinseed with a drop or 2 of white to add opacity. i have a ton more browns since then too so ill likely play with that side too, but i liked that one alot.
