Mutt is a muted brown with a gilded bronze sheen. It doesn’t read taupe to me–it’s too warm and golden for that. Like the previous two shades, it can be built to opaque color coverage or applied as a sheer wash of color with less product. Urban Decay Suspect is a little more yellow-toned. MAC Magical Mist is a bit grayer. Urban Decay Juju is less red-toned. Urban Decay Spotlight is lighter.
