MAC Moth Brown Eyeshadow Swatches, Comparisons, Dupes

NARS Lhasa, MAC Moth Brown, Urban Decay Mushroom

Possible dupe ideas: NARS Lhasa, MAC Moth Brown, Urban Decay Mushroom

I try not to get pulled in by the MAC limited edition product hype, but I do love my purple/taupes, so when the recent MAC by Request collection was released, I ordered one product – the eyeshadow Moth Brown.   It’s already sold out (though available overpriced on Ebay) so instead of a review, I have comparison swatches for you today.   The two most similar shades in my stash are – luckily – both permanent: NARS Lhasa, and Urban Decay Mushroom.
Swatches are done without primer, with a sponge – tipped applicator. Click to enlarge.

As you can see, the color family is the same, and the shade is very similar in all three eyeshadows. The biggest difference is the level of pigmentation – Lhasa is fairly sheer, Moth Brown has medium pigmentation, and Mushroom is very pigmented.  If you apply Lhasa or Moth Brown over primer they will – of course – appear more opaque and pigmented.

Everyone has different ideas of what is close enough to constitute a dupe, but I personally would consider Lhasa and Moth Brown almost-dupes; different in swatches, but identical on the eye.  Because Mushroom is more pigmented (and has more metallic shine), I don’t think it’s a dupe, though they might be close enough that you don’t want to own both.

Would you consider any of these three eyeshadows dupes?
