That looks like a Chanel blush to me. I see a lot of stars use them. They look like that. They are expensive, but it's because most of the colors blend so darn effortlessly.
Note: These colors do look different on the face vs. tested on the arm. If you are interested in them, do look at them in natural light rather than in the store to see how they really look on you. I find department store lighting is not the best for testing makeup.
