Funny you asked about Regard Perle. I have been meaning to comment on it for the last week! When I first got it, I was actually sorry I did, and was about to put it into my "to sell" pile (which is growing but I haven't been selling!). I decided one morning to give it another try though, and now I love it. I know this sounds crazy, but ultimately, the difference was that I applied the colours differently and used the metallic warm beigy colour wet. So I basically used the pink shade over my entire lid and up to the crease, then the beige colour applied wet (with MAC's fix +) on the inner half of the lid, and then the dark green shade on the outer third. I apply the green shade dry, and then apply it wet just on the outer corner to intensify the colour. I then really lightly apply the whitish colour over the crease, but not all the up to the browbone (it's just too light for that on me).
So to sum things up, I now love this quad!!! Strange as it is, a couple of my quads have been much more appreciated when I have applied them wet because I find that the baked pans (not sure if it's the same for the U.S. version), are really enhanced that way, it seems to bring out the true colour. I also find that this quad can be worn with both pink and peach blushes.
