Again, I am not Larry. LOL But ......
I believe Larry only uses the Alumilite colors. I don't believe he ever measures, instead he dips his stir stick into the color and mixes to eye. As a result, I doubt any two batches would ever be the same.
Nevertheless, Alumilite has white and red, which would give a good pink color or in the right mix a "pink flesh". Alumilite also makes a color called Caucasian.
I suggest that if you know your "additive" color wheel, and you have the colors that Alumilite sells, you can find a color close to what you are calling flesh color.
