MAC Relaxation is a very cool-toned, light-medium pink with a luminous finish. It is a limited edition blush that retails for $22.00 and contains 0.08 oz.
MAC Relaxation Casual Colour Lip & Cheek Colour ($20.00 for 0.43 fl. oz.) is described as a "warm pink." It looks more like a subtly cool-toned light-medium pink. It reads cool-toned when I wear it as a blush and as a lip color. As a blush color, it's rather light and spring-like. MAC Pink Tea is pinker. Bobbi Brown Nude Pink is similar but matte. NARS Gaiety is much bluer-toned. NYX English Rose is comparable. Make Up For Ever #4 is pinker, brighter. On lips, the coverage is opaque, and the color seems less cool-toned but definitely doesn't look warm against my skin tone. MAC Lazy Sunday is lighter, more white-based. MAC Snob is cooler-toned. MAC Enchantee is more muted. MAC Dress It Up is fairly close.
