I can't say anything without detailed error text

the chameleon gene seems to be unusable, game spits out an error upon trying to use a xenotype with it

Real life Chameleons change their color as a reflection of their mood.
Bright and colourful when they are excited = fighting and mating.
More mutted and darker collor when they are feeling submissive or relaxed, ie. admiting defeat in a fight or showing they are uninterested in mating.

Maybe this mod could be modified make human pawns with the Chameleon gene comunicate their mood.
