About More Hair Colors + Improved Hair Genetics

I would like to request an update to The Sims 4 that expands the variety of hair colors and improves the genetics system for hair inheritance. Currently, even the  horses have more swatches than Sims, and hair color inheritance is very limited—children can only inherit their parents' exact hair colors, with no variation beyond that.

It would be great if hair genetics worked similarly to eye color,  where traits can mix and lead to more natural variations like you can get green eyes when parent has hazel eyes. For example, a child of black-haired parents could have dark brown hair, or a child of light brown-haired parents could have dark blonde hair. Shades of auburn and copper could also transition into richer or lighter versions instead of being strictly limited to the parent's exact color.

This change would add more realism and diversity to families, preventing the hair color system from feeling too repetitive. I hope you consider expanding the hair color selection and improving genetics in a future update.
