I like the scent of grapefruit and have been wanting to try Pink Grapefruit. I really like it...it's a little sweeter than the regular Grapefruit fragrance I have. The regular grapefruit one is nice too, but tart...I just prefer a little more sweet.
For the pink color, I used Pink Oxide from Brambleberry. I haven't been using oxides much in CP because it takes more effort to get them mixed in well (I would use a small amount of the oils to mix in the oxide). I liked working with micas better. So when I ordered supplies this past December, I got a bottle of glycerin to see if it would be better at mixing in the oxide. What a difference...the oxide mixed in like a breeze!
I used 1 teaspoon of the pink oxide and wondered how light of a pink the soap would turn out, as there's unrefined shea butter in the recipe. It turned out a nice pink color...and in person, I can see a hint of violet undertones.
