Recently MAC launched a Limited Edition Collection called StyleSeeker, and i got those two blushes that instantly became my top favorites right now as soon as i used them.
The bronzy one is called Worldly Wealth and it has a frost finish. I like to use this just like a regular blush and apply it the same way and pulling it a bit down to the hollow of my cheeks, but i avoid the apple of my cheeks.
The peachy color is called Supercontinental and it has a satin finish, i like to apply this color on the apple of my cheeks only just to give a pop of color with the bronze (Worldly Wealth).
