Definitely Wet n Wild Nutty. Everything about it is amazing. But it's a frosty shadow. Did you want matte, shimmer, frost or...?? I've got another one by Joe Fresh, a matte shade called Smoke. It's a really nice, slightly grey-mauve-taupe. Very pigmented, blends like a dream. Picked it up last week for $1.94 in a sale bin. Normal price for their shadow singles is $4 for 1 or $10 for 3. They're very good, actually. Not to mention affordable. But I don't think that this brand is available outside of Canada. Although you won't find it in a drugstore, you could also try Kryolan. Their shadows come in huge pans compared to most brands, they are very affordable at about $8 or so where I live (even cheaper in the US), they come in many shades, and are pretty amazing. I have some of their stuff & love it. Just find somebody who's selling their stuff online, or maybe a makeup supply store near you carries their products & can order a specific shade in for you. That's how I get my Kryolan products. I believe CRC still sells some of their stuff as well. Another option is Makeup Geek eyeshadows, but also not in drugstores. Worth a look, however. Swatches of all her eye products are on her website, which helps when choosing. They're $5.99 for single pans (like MAC's), no compact, or $7.99 for a single compact. A lot of her eye products are very good. I've got quite a few of her eyeshadows and really like most of them. I can't think of one in my collection that's taupe, though. I do have Moondust, but it isn't what I would consider 'taupe'. Take a look at her website. You might disagree with me
Many people disagree as to what 'taupe' actually is. It's crazy how many variations there are with just this one neutral shade....greyish taupes, brownish taupes, mauve-ish taupes, purple-ish taupes....and of course the finish changes that too, whether matte, shimmer, metallic, frost, duochrome, or satin. Good luck
