I just finished playing with all of my products from this collection, and these are my thoughts. I am MAC NW20 for reference.
Pink cloud is very pretty, and yes it did show up on me - barely. I ended up pairing it with Rose Tourbillon. Pink cloud will be too light for most people to use alone as a blush. When applied in combination with a darker color, however, it gives a very pretty "glowy" effect. I am going to use this more as a higlighter. I doubt that I will be able to use it alone as a blush even in the winter when I am more pale.
Gris exquise is a nice matte, true grey shadow. It is lighter than MAC Hocus Pocus when applied over UDPP. I used it in combination with Hocus Pocus, the triscuit, and MAC Texture. I applied: texture very lightly in the crease; GE over most of the lid except the inner corner; HP just on the outer part of the lid making a v; the taupe part of the triscuit in the inner corner; and the pink part of the triscuit to highlight. GE is a nice shadow, but HP is nicer. If I had to pick one, I would definately choose HP over GE.
The triscuit... Before using it brush off the glitter overspray - unless you love glitter. I didn't brush enough of it off the first time, and it was a complete glitter mess. I ended up having to wipe all of the fallout off and reapply my foundation around my eyes. Once I got rid of the glitter, I was very happy with the results from this product. Swatches online make all of the colors look like white highlighter. Using my brush, I picked up a definate pink, taupe, etc. I used these areas of the triscuit alone as shadows and not highlights over other colors. I can get a similar look on my eyes using Prance, HP, Texture, and Blanc Type. I didn't use the triscuit on other parts of my face.
