More hair customisation with the colours would allow for much more unique player expression

for example multicolour hair, most basic example would be 2 separate hair colours with a basic uneditable gradient

brown hair at the roots and a gradient transition in thee middle to another colour at the ends

however I think a feature for customisable gradient (ex: a slider to change how close to the root of the hair the gradient begins, and how harsh it is) if you have a slide to the max the gradient would effectively disappear and the colour would just start at full value at the user defined location on the hair

more options would be the angle the gradient is located so instead of the colour gradient stating halfway down the hair you could use a slider to rotate the angle of the gradient so you could have dual tone hair split down the middle of the head

(I hope my poorly made diagrams convey my idea well)
