Could there be a patch so toddlers and children can have "unnatural hair colours"?

This is a must! I traditionally make Candy Bher and her sister have pink and blue hair respectively, pink and blue eyes too, etc, colour themed, and it’s annoying seeing their grandkids get the eyes but never the hair. In sims 3 I’d get constant surprises of bright neon hairs from a punk rock sim or an alien hybrid, if they married a regular hair colored sim then you’d maybe get a generation of regular blacks and browns and blondes but then their children would end up with their grandpas crazy shade and it was so funny, I wanna have that again and pray EA patch toddlers so they genetically get these hair tones. Also add more if they’re never gonna patch us a colour wheel. Add more so we don’t need one
