Of course, there are a gazillion caveats to my findings. It's only me, blah blah, I only used one eyeshadow palette, blah, maybe you use a different amount of eyeshadow than I do, blah blah blah.
There are a couple of things that I want to draw specific attention to, however. I used my Coastal Scents Thrill Ride eyeshadow sample (because it is small and fits on my scale). This little quad actually has really nice pigmentation. I also used my beloved MAC 239, 219, and 217 as brushes. They are damn good brushes. It would not surprise me at all if using lower quality brushes and shadows resulted in using more eyeshadow per application. I don't have the data right now (perhaps it is something I will investigate in the future), but I would strongly caution you against generalizing my results to that terrible ELF palette you bought on sale for a dollar.
Another thing that needs to be considered: you aren't going to use an entire palette. Let's be real. You're going to hit pan on your three favorite shades and you're gonna be done. Or, maybe you are a super frugal lady and you'll do better. Still, at some point, you're only going to have two colors left and they're not going to go together because of course. It's the Murphy's Law of makeup. This is interesting as a thought experiment, but I wouldn't count on wanting every last billow of eyeshadow dust that your palette contains, especially when the majority of the colors are long gone.
