I am not sure about the eyeshadow. I had so many of those graduated compacts as a teenager. I don't know if I'm ready for it again.
Dior sometimes make quads for spring/summer. Maybe they think makeup should be less elaborated in summer (shaking my head in disbelief). At least the colors in the quads are often more neutral than the colors of the quints. Of course I don't know yet, but I guess the colors in these spring quads are quite sheer - a sort of a color wash. I am looking forward to play with them, but I'm not in love yet.
