yo you might wanna change up how colours are done
1. looks like some of the base shades for body parts arent 100% white which means the colour/shade isn't gonna be 100% accurate so if you make a fully one colour girl some of the parts might be off from the rest
2. the shading uses the same colour as the one you pick for the base so it lacks depth it'd otherwise get from popping up the saturation and sliding the hue a tad
3. cuz' the gloss is 100% white, it's prolly gonna glitch out whenever you have another pure white/100% lightness colour so you could use the hair colour for it (tho i kinda prefer the plain white)

i only used a white skin for the demo cuz the difference would show up much better (notice how much more visible the shading is now), reworking the colour system should be useful for all other colours too tho
