MAC Cold Front is a very cool-toned, light lavender with a frost finish. It is a limited edition lipstick that retails for $19.00 and contains 0.1 oz.
MAC Cold Front Lipstick ($17.00 for 0.10 oz.) is a muted, grayish lavender with cool undertones and fine pearl. It had medium pigmentation, which was somewhat buildable, but it did not apply as evenly as it should have, so it was harder to wear it on its own but would perform better layered on top of something to add shine and coolness. The consistency was slightly more shimmery in feel, though I would not have described it was rough. This shade wore well for four hours and was neither drying nor hydrating.
The Metallic Lips collection features a new (and limited edition!) finish, Metallic, which is supposed to be "rich colour [that] melds with smooth pearlized chrome." The range of shades is described as "vibrant, intense, [and] on-trend." The coverage varied from shade to shade--anywhere from semi-sheer to semi-opaque--but many shades look like they're more suitable for a subtle look or for layering on top of another lip product to add a more shimmery finish. The majority of shades featured finer shimmer, which translated to a more foiled, reflective look, but a few had some shimmer. The wear was between three and five hours, depending on the shade, and most shades had some slip but were not slippery overall, so they were comfortable to wear but not hard to maintain. They were vanilla-scented but have no discernible taste.
