MAC Linda is a moderately warm-toned, medium-dark orange with a satin finish. It is a limited edition blush that retails for $39.00 and contains 0.35 oz.
MAC Linda Robert Lee Morris Powder Blush ($39.00 for 0.35 oz.) is a medium-dark, almost burnt orange with warm, reddish undertones and a satin finish. It had semi-opaque, buildable pigmentation that applied evenly to bare skin and blended out without issue. The consistency was smooth and finely-milled; the blush felt more velvety and refined than MAC's typical powder blush (including the previously released version of this same shade). It stayed on well for eight and a half hours on me.
P.S. -- These blushes are substantially large than MAC's regular blushes (0.21 oz.), so the price per ounce difference looks more like this: $109.53/oz. (regular) compared to $111.43/oz (this one). That being said, powder blushes take forever to use up so I don't think that more is necessarily more here for every person. The packaging is unique and more egg-shaped, but it may not be practical for everyone.
