I layered China Glaze Latticed Lilac from their Crackle Metals collection over Essie Sew Psyched. This was a good combination. With the flash, you can really see the lilac. Latticed Lilac looks silver in some light also.
Here it is without the flash.
This is Sew Psyched on it's own (pre clean-up). It has a shimmer effect to it. It's a grayed green color.
