I'm NW20 with blue/grey eyes and bought both (well, I already had Moth Brown from Madame B but you know). I also bought Playful but that's just to go with Passionate for pink looks.
I am NW20 blue/gray eyes and blonde hair, and I bought all... I think any of them would look great for you too.
If you're trying to limit your spending, I'd get at least the ones you're considering!!
Moth Brown is a great color that blends with many shades. Of course, I had it already from a previous collection. I bought Whistle and Macgic Dust. Magic Dust reminded to too many other neutral colors that already own, so I returned it.
