The Cheek& Cheek blush duos comes in 4 permanent shades currently (and shade #05 limited edition for holiday 2011 I think). The color names are:
 Candy Flowers
 Rose Tiara
 Kiss Gerbera
 Love Blossom
I'm reviewing #01 Candy Flowers here.
#01 Candy Flowers up close: the left hand side is a soft pastel pink, it's quite a pure pastel pink and does not have peach tones or rose tones inside. The color on the right looks a bit more true orange in real life but in photos it looks more like an orange coral. Both shades have some shimmers inside (mostly silver) , while visible in compact and in photos I consider it subtle on well primed skin.
Also comes with a very miniature blush brush- I consider it rather useless since it is just way too small. Nevertheless for touchups I think it's sufficient. The bristles are very soft which means it often doesn't pick up quite enough powders.
Back of compact, the color code (01) is on top right corner.
I've taken quite a few swatches, the left shade is as I described, a true pastel pink. It doesn't look very 'fake' on the skin as pastel shades sometimes would, as it is sheer and translucent enough.
The right shade applies quite corally peach/ orange on the skin (and very pretty IMO), especially when blended with the pink slightly.
On the bottom of the swatch is the shade when both colors are blended together.
The blended shade outcome is more visible in swatch pic below: you get a soft peachy pink shade. You can add more peach into it by applying a bit more of the orange side.
You can see the very sparse shimmers are only slightly visible in photos.
Overall 5/5 for these blushes, especially given the price. I mean they are not going to be better than Jill Stuart blush quads (which these were often initially compared with), but the pigmentation is decent and colors are gorgeous. The finish is also lovely if you use a proper blush brush.
I do not experience fading or oxidation with this blush even after a full 8 hour wear.
I picked a few of the other colors from the same range which I will review overtime.
