When I created a household with 8 people some of them turned a black-blue color...

I was making a household of eight sims for a challenge and 2 out of the 8 turned a black or/and blue-ish color for some reason. I thought it was Sims trying to load the sim so, I left the game alone for five to ten minutes and it still had a the same color. I exited out and returned to Main Menu then went back into the world but the sims are still that color. Oh and in there portrait their still there original color.
