More hair colors would be great, but honestly what's worrying me the most is how all the Maxis Match CC would need updates too. I have hundreds at this point. Kinda seems like a huge hassle to go back and update all of that too? Yes, CC is absolutely not EA's responsibility at all, but we're already four years into this game. It seems a little.. late.
Still, I wouldn't mind getting new swatches for every official hair. Bring it on.
A color wheel for hair, eyes and skin, with any of the existing swatches as a base, would be even better. Give me a hue/saturation slider. Thanks.
