I must say I don't really miss more hair colors. It would probably mess with all the nice CC hairs out there, like it did the last time they added a bunch of new colors. At least not unless they adjust the DNA aspects, like sims inheriting not only the color but also say curls, hair growth, baldness etc. That would be an improvement.
Additioonal hair extensions/accessories would be nice though, like attaching stripes or a few styles of exra fluff/curls etc for the trend setting sims out there ;)
they can add them both we need new colors and new genetics. CC hair can be used for old hair colors too
