MAC All Year Red is a very warm-toned, medium red with a natural finish. It is a limited edition blush.
MAC x Min Liu All Year Red Cream Colour Base ($26.00 for 0.21 oz.) is a vibrant, medium poppy red with warm, orange undertones and a natural finish. It had rich, opaque color coverage--a little went a long way--with a smooth, moderately emollient consistency that was thin, lightly tacky, and had a natural finish. I found that this particular shade seemed to dry down a bit more than most Cream Colour Bases after a few minutes, so it had more of a "natural matte" finish on my cheeks. Though the formula is supposed to be buildable, this particular shade is very pigmented, and I'd say that to get sheerer coverage takes an incredibly light hand and a fair amount of blending. Medium coverage was easier to obtain with using a light hand and just blending and diffusing the edges with a stippling brush or fingertips. It wore well for nine hours on me before fading noticeably.
