I got my package tonight with my two extra Runaway Reds (batch AA1) - they're on the left and the middle.....on the right is my MAC Me Over Runaway Red (batch B41)
In the tube, they do look different. The S3/C3 versions look like an orange rusty red.
When they're swatched, I don't see a discernible difference in the colors. They all three have the same hue and fuschia sheen on my skin. I'm a lefty, and I swatched the lipsticks with my right hand, so the pressure and swipes varied with each lipstick I put on my arm lol, but you can tell they have the same base color and sheen.
It's rather odd that they would look so different, and that they are showing up as different depending on which surface they are swatched on. In my case, I am going to hold on to my back-ups because the colors are relatively the same on me.
