The alien skin tone does not appear to be truly dominant unless one parent is homozygous for it. Like custom skin tones, it is outside the 1-4 range, and is generally treated as dominant, but how this is expressed depends on other conditions. The alien skin tone appears to be a special case. While one will be shown as "dominant" and one as "recessive", the game itself does not treat any normal skin tone as dominant. In SimPE, these genes will be shown as "SkintoneRange". For example, a baby who gets a gene for tan skin and one for dark skin may have tan, medium, or dark skin. Within that range, all skin tones are equally likely, and which one the baby has is determined at random.

However, if a Sim receives two genes for normal Maxis skin tones, those genes define the ends of a range in which 1 is light skin, 2 is tan, 3 is medium, and 4 is dark. It should be noted that, while alien eyes are dominant, the alien eyes will look identical to brown ones, should the Sim not also express the alien skin tone. The other will be carried as a recessive and will be shown as such in SimPE. That color will be visible, and that gene will show as "dominant" in SimPE. However, if the baby gets two dominant (or recessive) genes for eye color or hair color, one will be randomly selected as "dominant". If a baby gets a dominant and recessive gene for eye color or hair color, the dominant color will always be visible. I could not get most of the colours to look nice and I refuse to give you crappy quality cc.The game considers certain eye colors and hair colors as dominant and some as recessive. Notes: I have not included all colours for the frosted/ombre hair from Perfect Patio and Backyard Stuff. Only install files for packs that you have installed. The files are organized by pack in the folders so you can pick and choose according to which packs you have. Put folder in Documents > Electronic Arts > The Sims 4 > Mods.The hair is genetic, meaning that children can inherit these hair colours from their parents. I’ve recoloured all the child and toddler hair in the game (base game + all packs thus far) to match the 6 unnatural colour swatches available to adults purple pastel, hot pink, dark blue, turquoise, green, and white. I was so frustrated by this that I learned to recolour hair just so I could fix it. I just had one problem kids and toddlers don’t have any unnatural hair colours so they couldn’t inherit the unnatural hair colours of their parents.

I’m not much of a CC creator but a while back, I wanted to play a perfect genetics challenge in The Sims 4. Genetic Unnatural Hair Colours for Kids & Tots (Base Game + All Packs)
