More Natural Hair Colours?

The Sims 4 has a strong focus on the customization of sims, however, I feel that like hair colour options are severely lacking. Its strange that we can go into so much detail editing our sim's faces and bodies, yet there's a really limited number of hair colours, which I find is a huge aspect of a sim's individuality. There have been more unnatural hair colour additions, but I believe more natural hair colours should also be added. Even if it's only a few more in-between colours like a more reddy brown or lighter/darker blondes I think it would be a nice improvement, like how they added more in-between skin tones.
What do you think?
