Swatches (Satin Taupe (left) Naked Lunch (right))
If I remember correctly these two e/s were the first ones I purchased from Mac.
They both are gorgeous and compliment each other well.
For everyday looks I usually have Naked Lunch as a wash over my lids since its quick and simple to do.
Whereas if I'm going out for dinner etc I will add Satin Taupe to my crease just to add depth.
Mac eye shadows in general last me ages so in my opinion they are definitely worth the investment.
