Pink all the way. Too light and you won't notice it really, pink is just the right balance so it slightly blends into the rest of my face while still being noticeable. I usually avoid bright colors like red or wine because it brings to much focus to my lips.
Well, girl 2 is doing something odd with her lips... so, it makes the picture less flattering. It all depends on skin tone. Out of those pictures, I pick the top one because her lips are less weird and the color is nice.
