There are differences, but they are slight.
Turquoise pigment jar: Silver label with name of pigment, A99 MAC Pro, and the following words about the name, which is not centered "Pigment Colour Powder / Poudre Eclat De Clouleur." Around the edges of the label, it says "Make-up Art Cosmetics, Toronto -London-Made-in/Fabrique Au Canada." The markings on the back of the pigment jar are also slightly different. It features a hand with a book (precautions I think, the "e" in between the gram and oz weight, and the recycle arrow is larger (same size as 2006 Golders Green), and is on the same line as the address.
Red Pigment Jar: A52 is printed on the bottom of the jar itself. The label is clear and it just says red on the bottom. There is no precautions book on the side of the jar like Turquoise or Golders Green. The 'e' is smaller and on the left side of the oz. The recycle arrow is small and is at the very bottom. (This is authentic because I bought this at the pro store).
Golders Green Jar: A16. Silver label on bottom with name and A16. The precautions label is there on the back in same position as turquoise, the 'e' is between the grams and oz in center of jar's back, and recycle arrow is large again and centered with the address.
