Since I had some back to MAC burning a hole in my pocket, I picked up Riveting Rose and Indigo Pink today. These colors are beautiful and nothing like what MAC currently has.
Here are some swatches:

Riveting Rose is more of a purple on me. I can definitely see the blue pearl in it. But Deep Burgundy, no... Its not frosty at all, but I can see why MAC calls it a frost- It has a beautiful sheen to it. Almost like a duo chrome shadow. I love it for its texture and color. Its a very unique lipstick shade. I know it was compared to Hang Up, but on me, its nothing like that, its a shade of purple.
Indigo Pink is a true "Deep Burgundy with Blue Pearl". The two go together VERY well. Indigo Pink over Riveting Rose is a very high gloss combo!
