There are a few hairs I didn’t recolor: All the hairs and eyebrows featured in Freedri’s Dyed Hair for Toddlers - Hair and Eyebrow Recolours and one hair from Backyard Stuff were the tips of the hair are dyed I did use the colors of the adult hair texture if the child hair had the same mesh (like the Paranormal Hairs).
The colors of the hairs are a little bit off than the adult versions of the hair. Some things to take notes: I never made CC before so it may be imperfect. So I went through all the hairs and recolored them. Wanting the fun unnatural hair colors of the adults to be genetic for your sims? Same.
