Anyone Know How Genetics Work With CC

So I’m mainly talking about alpha hair. Obviously the colors don’t often correspond with their maxis counterparts so I was wondering how they combat this? I had a sim with maxis brown hair have a baby with CC white hair (that was the first slot in hair) and then all three of their babies had brown hair. So I was like “maybe that’s just cause the brain saw an unrecognized color? So they went with the recognized color”. But I wanted to test it. So I made a sim with the same alpha hair, and then some random blonde girl and had them have six babies. Three blondes, a brunette, and two white hairs?? Despite the white being the last color on the palette and his white being the first color on the palette. Is there come game mechanic to help CC better translate to in game genetics?
