To show what I mean, I've added adult Sims with the same hair colour in the background, so you can see the colour likeness. So I decided to create 5 funky colours per hairdo for the toddlers: And while I get that grey(ing) hair is a bit odd on a child or toddler, I really love the bright, funky colours in the game.
Kids and toddlers have 9 colour options per hairdo.
You know how teens, (young) adults and elders have 18 colour options for each hairdo? Well, kids and toddlers do not have all these colours.
