I want to tell everyone that I was looking at the update book again and the symbols next to these pigments were interesting.
Mauvement had the normal repromoted, limited edition symbol.
Mega Rich had the new shade, limited edition symbol.
Museum Bronze, Antique Green, Vintage Gold, Copperbeam, Heritage Rouge, and Blonde's Gold all had a symbol meaning new shade, permanent at MAC Stores. I don't know if this was a typo or not. If it's not then YEY WE DON'T HAVE TO BUY THEM ALL AT ONCE!!! 8D
