The blush is called 01 You sweeten my day! As I said the sweater design with heart in the middle is really cute. Sweater pattern is light pink, while the heart is more of a deeper pink. Sweater shade to me looks like a highlighter, but it actually gives a lighter sense to the whole blush. Heart is obviously darker and has most of pigmentation.
Pigmentation seemed horrible in the beginning, because the upper layer was so hard, but it actually becomes softer and gives some color. Saying that, it is still very light shade in general and it’s definitely not strongly pigmented. You need to build it up quite a lot to get it noticed. I’m sure this will be a problem for a lot of people.
