This is an experimental LORA helps you control the hair colour of specific male and female characters in your scene by adding tags for hair colour and gender. While hair colour tags already exist, this applies those tags by gender with the intention of forcing the hair colour. It works best if you don't specify the hair colour elsewhere.
The available tags combine hair colour and gender:
red_girl
brown_girl
black_girl
blonde_girl
white_girl
pink_girl
green_girl
blue_girl
grey_girl (v2)
light_brown_girl (v2)
And for boys:
red_boy
grey_boy
blonde_boy
black_boy
white_boy (v2)
brown_boy (v2)
Your mileage may vary.
