I'm an NC30 and the blushes that I find reaching for the most are MAC Margin, Benefit Dallas and Georgia blushes. Margin is a peachy/coral on me with slight shimmer and I find that this goes well for both day and evening looks and it compliments most e/s colours I use. Dallas is just lovely on me...it's a rosy brown colour that gives me this bronzy after workout look which I really love. I reckon most skintones would be able to use this as an overall face colour too. And Georgia...gosh this is my first love, the blush that made me fall in love with blushes lol. It's sheer yet buildable, and this is the perfect blush for day looks and you can never put to much of this on your cheeks. And it smells really good too.
