Illamasqua Muse is a very cool-toned, dark teal with a cream finish. It is a permanent nail lacquer that retails for $17.00 and contains 0.5 oz.
Illamasqua Muse Nail Varnish ($14.00 for 0.5 fl. oz.) is described as a "deep teal blue." It's exactly that--at first glance, it's more blue than teal, but it's not just blue. There's teal, blue, and enough depth to call it deep. The finish is creamy, and the color is opaque in two coats (but nearly opaque in just one). I had an easy time with the formula, because it wasn't too thick or thin, so the lacquer flowed evenly across the nail and didn't bubble. I typically get a week's worth of wear out of Illamasqua's nail polishes.
