NARS Gaiety is a very cool-toned, light-medium pink with a satin finish. It is a permanent blush that retails for $30.00 and contains 0.16 oz.
NARS Gaiety Blush ($28.00 for 0.16 oz.) is described as a "bright candy pink." It's a cool-toned cotton candy pink with strong blue undertones and a mostly matte finish. I remember some readers inquiring about its similarity to NARS Desire, which I did not own previously, but now that I do, I can say that it's far, far different--Desire is darker, richer, much more intense overall. MAC Full of Joy is lighter, more purple. MAC Peony Petal is darker, pinker. MAC Azalea Blossom is more purple. MAC Briar Rose is pinker.
