1. Black
Specifically: black cloth, or shoes. I can do black armour easily enough (paint black, highlight with something shiny), but that doesn't work for clothes or shoes. I've tried a few variations such as grey highlights but they don't seem to look right to me (maybe its just my grey not being dark enough or something?). I've got plans for a couple of BB teams to use black cloth in their uniforms so want to figure out how to do this.
2. White
Kinda opposite to above... I can sort-of do white cloth (got some tips a few years ago when I started my pro elf team), but struggle with white metal. I want something white and shiny but am not sure the best way to do it.
3. Hair
Bit of a trickier one maybe... I can do brown hair - paint with dark brown, highlight with lighter brown. Easy enough. I can even do silly hair colours like blue and green (again, pro elves

Thanks for any help!
