For once, Jeanie’s greenish skin tone is intentional!

And speaking of greenish skin tones, if you’re still seeing that green tinge on other characters besides Jeanie, the reason is most likely due to your monitor’s color temperature. If it’s set to around 6500K, everything will look normal. But some programs, and some monitors themselves, will let you set the color temperature to a custom value. Unfortunately, the color palette that CD Rudd uses for skin tones suffers badly when displayed on a low color temperature monitor (around 3000-4000K).

So if you’re seeing those greenish skin tones, look into calibrating your monitor’s color settings. Google has lots of results on how to do that.
