I need help w a lipstick color!

okay here it goes..

so I ran out of 6 mac items so I'm gonna go today to go grab a free lipstick, thing is I have No idea which one to try next? especially since I just plan on grabbing one. don't wanna spend any money today. kinda want a shade different from what I already have. here's a list of shades I do have :
myth
snob
saint germain
lovelorn
up the amp
a red shade in prolong wear
and a peachy colored creamsheen

thing is I'm only able to grab a regular lipstick, no viva la glam, no creamsheens or limited edition. which I'm bummed about I really wanted to try that new Nicki Minaj one. anywho. I've been eyeing yum yum candy But I have a makeup forever shade that's damn near the same thing so idk.

basically I just wanna know what colors you guys like and if you have any suggestions for which route i should take??? thanks!
