Once upon a time, I owned absolutely zero taupe eyeshadows. I was convinced in my naivete, that because I looked horrid in any clothing and lip colors with any brown tones, that that same principle applied to my eyes as well. However, after hearing again and again on the makeup boards how so many people loved taupe eyeshadows, and seeing that Sephora was clearing out their entire stock of Napoleon Perdis, I hemmed and hawed and eventually went home with a color disc in #40, Irid. Taupe for the bargain price of $6.
Since it is the first of the taupes, I'm drawing a slight blank on shades to compare it to (I want to compare it to RBR Gracious Arasari, but it's currently floating around somewhere in my room). As I swatch more taupes, I may revisit old ones for comparison. Feel free to ask if you want any compared to shades you may find similar.
