I've had a chance to wear the 3 that I ordered and here's what I think of them...
Diffused Heat is my favorite by far. It's a pretty, bright coral color that looks great on my pale skin. It's a keeper.
Radiant Magenta is going back. On my cheeks, it looks very much like DH. RM isn't as bright and is more pink. The RM I received, had more blush than powder but I still had to do more than a few swipes to get the color to build up. It's going back
I'm undecided about Dim Infused. I need to give it another try. It's a very pretty peach on but I have so many peach blushes, I don't know if I need another (especially when it's $35).
I don't think I'll be getting any more of these. They are great quality but I don't think there is anything unique about the colors - both RM and DH reminded me of my Horizon de Chanel blush (best blush purchase ever!). These just aren't 'wowing' me. I think if I mix any of the blushes I have w/the ambient powders I have, I can get the same effect as the Ambient Blush.
