It was with this rather iconoclastic idea in mind that I purchased MAC Mehr. It's a medium dirty antique pink matte. I think it's been released twice with a couple of niche MAC collections but whatever; it's not ridiculously unobtainable.
I don't buy this shiz about warm and cool colouration as far as living organisms are concerned. If you have any art or colour training at all, you'll poop on it with me. For instance, my hair is cool, unless I dye it, (which is always) and then it is warm. My skin is both cool and warm; my lips are dark and cool, my eyes re largely warm but spotted with coolness. My neck is... I could go on. And on, and on. So let's cast that bollocks aside when we're wondering what will suit us. You can't rely on that criteria.
Overall it's a cool and pretty complex colour with ashy characteristics that will either come to the fore or be dialed back according to your own colouration; on some it will appear horribly corpsey, particularly in the bluer light of winter. There is a very subtle sheen when applied thickly; when thin, Mehr is flat and can emphasize dryness and lines so if you have chronic problems in that direction, it's one to skip. I tend to mix it with a little bit of balm or something like MAC Hot Tahiti to soften things up but it is very tenacious on the mouth when worn alone, never bleeding or really budging. I apologize for the lack of suitable companions for comparison in the swatches, but you can see how it is not remotely like any of the other pinks you might have encountered personally.
