MAC Cheek is one of my favorite blushes, but I'm an NC20 and it is appears very light on my skin. You might want to check out NARS Gilda blush; I have that one also and it's a great peachy pink blush with a bit more pigment.
I'm a NC40 and I just bought mac uncommon creme blush. Its really nice subtle blush, just the right amount of healthy colouring on your cheek without being too much. I was a bit dubious about it as its pinky/peach. But i've really like it now! Check in out!
I think Cheek will show up. It looks pale in the pan, but it's very vivid on. I'm NC25 and I have to go easy with this one. I could see this on a deeper skintone; it's sort of the softer, muted version of Fleur Power.
Thanks everyone! I think I'll check out NARS Gilda, uncommon creme blush and Fleur Power. I already have MAC Peaches which I like, but I'm looking for something less orangey. Thanks again.
