How would I go about changing the color of this modeled hair?
Ive been looking at these Zack Event blind box bjds and I love the proportions they have and Im planning to turn the Tattoo artist one into a custom.
I already know I want to dye the body and head a new color but im not sure about the hair, as I want it to be green with black stripes. Would it be good to use acrylic paint for both the green base and black stripes, or should I dye it green first?
Also the hair the original doll comes with is gray and Im wondering if I can dye or paint the green on the gray and if itll comes out bright, or if I should buy a 2nd blank hair set like in the 2nd image
