Color Wheel on CAS

We definitely need a colourwheel for hair colours. We have one for pets so why not for Sims hair. The selection of hair colour is very limited. In real life there is a huge variety of hair colour and on top of that people like to dye it other colours. A colourwheel would suit for creating Sims with both natural and unnatural hair colour. Also they should have sliders and more swatches for natural hair colours. At least add light brown, dark blonde, light red and auburn. I've never been able to get close to my natural hair colour in any of the Sims games (except for Sims 3, but I had to use the colourwheel to get that, but that was much better than nothing) The blonde from Sims 1 is much closer to my natural hair colour than any of the blondes in Sims 4.
