Nearly there

As you can see I've got a lone space in my MAC blush palette, and I have no idea what one to fill it with. Can you suggest one that I simply must have, that isn't too similar to the ones I have already?

Top row L-R : Peachykeen (my favourite ever!), Blushbaby, On A Mission

Bottom row L-R : Sunbasque, Stark Naked 

I can't decide if I need a pale peach, a pretty pink, a coral or even a deep plum... I don't know! What would you suggest?
