Yes, yes, yes! As another reviewer said...THIS is what I hoped MAC Satin Taupe would be.
Stray Dog is a beautiful plum based taupe, which is a fantastic compliment for any eye shade. It makes my green eyes really stand out. There are no silver or gray tones, which is what ruins taupe shades for warm complected gals like me. Nor do I see any brown, but maybe it depends on eye color and complection.
The consistency can only be described as "velvety" and the pigmentation is amazing. I can very the intensity of the color easily from very subtle and natural to very rich and smoky. It layers smoothly and blends beautifully.
I used this as a crease color over BE Vanilla Sugar, with a very dark purple (the very darkest matte purple the WNW "Lust" pallette) in the outer V and along the lashline. I finished it with UD 24/7 liner in "Rockstar". I'm very pleased with the look. Because I'm so pale, it's hard to achieve a smoky look with black and gray. They're just too harsh and too cool. So I choose purples for a smoky eye, and this really does the job nicely.
It's fairly pricey; $17 for one eye shadow is a little steep for me. But I think it will last quite a long time, which makes it a better value than a shadow that you have to layer and layer and layer to get satisfactory color payoff.
I've only recently begun to experiment with high end eyeshadows and I have to say that I am far more impressed with the quality of the UD eyeshadows than I am MAC. MAC shadows are nice, to be sure. I can't dispute that it's a quality product. But Urband Decay are just better, IMO. And, I don't have to go to the mall to get them, which is a HUGE bonus for me.
