Your character has a light hair and you can barely see your bush? You just want a black bush no matter what? Look no further! You can now choose the strength with which the hair dye affects your bush from 0% to 100% in steps of 25%. 0% is not dyed at all (black) and 100% is dyed completely.
It affects both Bibo+ pubes and BPF pubes. Make sure it has a higher priority than both of them.
And that's it, were you expecting me to write more about how to dye your bush? Just have fun showing it off. ♥
