Guerlain Parure de Nuit Pressed Powder & Blush ($67.00 for 0.35 oz.) is a limited edition is primarily a luminating product, but it can also deposit a faint hint of color on cheeks. It has a peacock-themed design with a good amount of details that actually survive past the first use (or three). The powder has four distinct colors: pale white, bluish-teal, pinked coral-red, and pale peach-beige. It's subtle, soft, and sheer. I was quite surprised at how well the design stood up to heavy swatching and lots and lots of passes with a brush--all done in hopes of destroying it--and I dug up a bit of the first feather to see if the colors ran all the way through (it appears to be so, and the brand's description seems to confirm that as well).
