@SheriGR Basically yes, it's mostly for a friend, cus she wants her sim to look like her but she changes her hair colour constantly irl!
@PugLove888 Makes sense, but as a programmer myself, I don't think it'd be too difficult to work out. Back in Sims 3, the entire thing was done in C#, which I use a lot, and the genetics code simply used the first outfit you made in everyday as the base colour. I'm not sure if you could change to a different colour in that game cus i haven't played it in a while, but I will check and report back
the other option would be to let the player choose a base hair colour for their sim as like, a button in the box for voice pitch and walk styles, and maybe put the favourite drink/food options back in there too 😛
Worst case scenario, I'll try and make my own mod
