Do you have a holy grail eyeshadow?

I'm curious to know what your holy grail eyeshadow is. I have several, but if I had to share just one first... it's the Urban Decay Naked Palette! This is a total must-have. It has all the colors I use frequently, so I find myself reaching for it every day, haha. I really like that there aren't any weird shades mixed in. The price is pretty reasonable too, so it's great value for money!
