I made this today, it is a first attempt with powdered buttermilk. I wanted a brighter purple, and at first it looked gray, but it is looking more purple as it sets. I tried something a bit different for me, I took some uncolored base out to swirl with, and colored the rest of the batch. This one, I swirled in the log mold, never done that before either, so it might not go clear to the bottom.
