recoloring a penis mesh?

[ladybandicoot]

I don't know how many people here play Berry Sweet Sims, but I do. 

 

For a long time I've been living with the dreaded 'black penis' due to the fact that none of my fantasy colored skins having a fantasy colored penis. 

 

I think I need to try and fix this issue. I just... can't seem to figure it out. I'm fairly savvy at recolors I'm just having a hard time trying to figure out how to do this exactly. 

 

If anyone can throw me a little nudge,  please do!
