Hey there girly...I've gotten obsessed with bright lips lately too...LOL Ok, granted this is coming from a girl who's too pale for MAC (except when I have a deep, dark tan...then I'm NC15 LOL), but I've seen these colors on some of the lovely WOC MAs, and they look absolutely stunning, so I hope it helps a little...
GAT is a lovely pink...if it's a bit more on the purple side on you, put Love Alert dazzleglass over it, it's totally sexy. Some other awesome pinks you could try are Impassioned, Lustering, and Trimming Talk (I just bought this one, and really love it...I was sold once I saw one of the MAs wearing it). I don't know whether or not it would be too pale for you, but Pink Nouveau is a really great bright, yet light pink.
GL, and I HTH you a little bit!
PS, you love Morange, have you tried Vegas Volt? It's REALLY pretty...and I think it would look lovely on you.
