Interesting, I guess they were using printed princess faces? I use a bit of a 350 for my princess face so I use blush or Mocha depending on the princess. This report does remind me of something tho, Whenever I make Jasmine I am never actually sure what colour balloon to use for her skin colour, now if I were to follow Disney then the blush balloon would be the closest match however I did have one customer tell me it was the wrong colour as she would come from the middle east so Mocha would be a better colour.
So now I always ask the person who I am making the balloon for what colour they would like the skin of their jasmine, I hold up the 2 colours and ask them to choose the correct skin colour for jasmine, most of the time it is Blush but sometimes I do get mocha chosen.
