Yeah that 1N lg looks very inviting indeed. I might get it, it seems like it would be too light but I think it might flatter darker skintones.
A friend of mine is NW 45 and she bought the Light Flush MSF and I don't even think it looks pink at all, more like a slight irredescence (sp). I would guess with your skin tone it would be exactly what the name implies, a light flush of pink.
