Color Wheels For Hair, Skin, and Eyes

I love how diverse The Sims is with the range of preset colors yo can choose from for ski and hair, but it's still more limited than I would like. I'd enjoy if we could choose precisely what color we want our Sims' skin, hair, and eyes to be. Especially with aliens, the skin options aren't very diverse.

And some of the eye colors for human Sims aren't that different from each other. I can barely tell the difference between the three hazel eye colors, but the biggest ones are the green (two of them) and blue eyes. I can barely see the difference to the point where I question why they even added two swatches of them if there's hardly a difference.

The hair one especially is annoying to me too. The "white" hair swatch is more gray on most hairs. The "dye" colors are either too vibrant or not vibrant enough. Or there just aren't enough shades. My biggest one is the "purple" hair swatch. That's not purple, that's pastel.

The darker skin tones also need darker hairs and makeup to go with them. My Sim would be super dark and it'd look great, but then the hair would be completely off and fake-looking because it wasn't dark enough. (I tried both black swatches of hair and neither worked.)
