For the look that Misschevious does, go for an icy mettalic gold, but other than that keep things matte. I've noticed that the sparkle can get very out of hand very quickly on dark skintones. For the lips, you can either go with a bright red, or a brick/berry red.
For the Badkitty look, keep in mind that it's dramatic and wild to begin with. So you can do drama within your framework of feeling comfortable. Keep the lips neutral like she does by using a neutral lip pencil, neutral lipstick, and sparkly gloss. I personally like hodgepodge pencil as a lip erasing color on myself.
