The new Pink Explosion seems to be darker and richer in color compared to the one from last year. Tumulte is lighter in comparison and does not have noticeable shimmers like PE. Malice is a dark coral with red undertones. Plum Attraction is a rich plum with fine shimmers.
With all four blushes, you will get rich pigmentation. Chanel excels at making very wearable and flattering shades. The texture is soft but not chalky. You can see the shimmers in Pink Explosion and Plum Attraction under direct sunlight.
Overall, I am a huge fan of Chanel's Joues Contraste Powder blushes. I don't think you can go wrong with any of the shades. Plum Attraction can be sheered out for a soft plum or almost bronzer like effect. Malice is a soft beautiful coral shade while Pink Explosion and Tumulte will be especially beautiful on light skin tones.
Bottom Line: These are beautiful shades to definitely check out. I personally did not pick any of them up quite yet because they are part of the permanent line. I will eventually go back to pick up Tumulte and Malice. I find the US formula much easier to work with compared to the baked formula. If you missed out on Pink Explosion the first time, you'll now have plenty of chances to pick it up.
