I saw the collection yesterday and like it, but wasn't swept off my feet at this point, so I didn't buy anything. I put on one coat of the nail polish and it was more silvery blue, but I think with two coats or more, the blue would be more pronounced. The IdOs are very pretty, Apparition is a smoky deep navy on me, and the lighter shade is like the nail polish, silvery blue. I like the khol too!
bis - I think Apparition is black-blue on paler skin, and on darker skin, it shows more as a medium blue.
