Blue Smokey Eyes are beautiful; It creates a more suttle look from the original!
Although, at Sephora it's ahrd to find one for only fifteen dollars.
If you want a good pallette for like ten dollars, you can go to a local department store and pick up
Prussian by MAC, it's $14. It's just as good as anything from Sephora, I'm actually suprised that they haven't cosigned.
But if you save up a bit more, or whatevere, you could get a really nice pallette from the Kat Von D, it's called The True Romance Eyeshadow Palette in Beethoven, which is about $30.
Hope this helped!
