After a long wait, I finally had some sunlight on my day off and was able to swatch my Clarins franken.
You can find the recipe on MUA here. L8B is a genius! I don't think mine is quite as good as hers is though.
This is one coat overtop another purple franken:
and two coats over Wet and Wild Extravaganza.
I think it's as close as I'm going to get. The secret ingredient is Colorama 40. It has the same color shifting pigment as 230, but not as much of it, so all the colors aren't has vibrant as 230. What do you think?
Thanks for looking!
