Hot or Not - Which colour treatment works best?

I'm working with the new character design for Rizzo and, as always, have gone down the rabbit hole of options. 

I'm trying to work out a colour-scheme that will work well with the UI of the game, as well as read well at small and large sizes. What do you guys think? Which is the most appealing and easiest on the eye? And which hair colour works best?

I know the difference will seem small but it's the sort of thing you get caught in a tailspin about, going round and round in circles! I need some extra eyes. 

Please let me know which variation you prefer!
