1.) My characters sometimes spawn in with weird colors of makeup, and I can't find an option that removes it entirely (I'm a fan of the all-natural look).
2.)About half-bunnies specifically: I can't find a way to set the color of the ears without messing up hair colors.  I know it's possible because some bunnies spawn in with ears that are different colors from all of their hair options, and Daisy's ears are a different color than her hair, too.  I wouldn't know about full bunnies because only having white and grey as fur options makes me want to stick with full-bunnies.

I downloaded this game a couple of days ago if that's important for anything.  I'm pretty sure it's the most recent version.

we need to reapproach the weird pseudomakeup coloring but for the hair-ear thing you should try coloring different part of hair altho generally ear/tail color is tied to hair if im not mistaken
