I have a small issue to address: The previous reviewer had some good recommendations based on color, but not on quality or price! Four individual MAC eyeshadows cost $60, whereas a Chanel quad is $59. Of course, if you purchase the MAC pans, the total is $48, so that could be a significant difference in price for some people. However, four MAC eyeshadows are .20 ounces, whereas a Chanel quad is .24 ounces. So even if you are comparing pans to to the quad, the price difference versus the amount you get is not really significant between brands.
Furthermore, I honestly feel MAC eyeshadows are of only average quality at best. Many of the shades crease on me, even with a primer, and they tend to fade very quickly on my lids. Chanel powder eyeshadows last 6-8 hours on me before I even add a primer, and after that, they last virtually all day. MAC eyeshadows also are not as finely milled as Chanel's, and I find them to be stiff at times. Of course, your mileage and preferences may vary, but I just wanted to add some insight into the other reviewer's comments.
As for this specific quad, I think Mystic Eyes is gorgeous, and surprisingly so. I'm a very cool-toned, pale (NW15) girl and I wasn't sure if these colors would suit me, but they really do. I love neutrals with a twist, and Mystic Eyes is just that! Pale, soft pink, warm silvery gray, rich brown, and gorgeous copper make for a super feminine, sophisticated palette! I love how this quad can offer a very smokey, sexy, dramatic eye, or a simple and work appropriate look. These shadows, like all the other Chanel shadows I've tried, work beautifully both wet and dry, and they are fun to use to line the upper and lower lash line. The pigmentation is very good. I think Mystic Eyes is a palette that could easily suit a lot of skin tones, because the colors are so universally flattering! I highly recommend it to anyone who wants a versatile, really well-done quad from Chanel.
ETA: I forgot to mention that this is the most shimmery quad I own from Chanel. You can still easily adapt the colors for a work look, but you may want to throw in a matte shade if you use any of the four colors for daytime. That was why I took off one lippie, but honestly I would rate this palette as 4.5 out of 5 if I could.
