Repaint experience

I am getting my kong ssj3 blue head sculpt for ssj3 gohan build here soon and need to repaint it, I got the blue because it was 60 shipped and the yellow is over 100 before shipping anywhere I look, my question is what might I need, obviously yellow and I would assume a shade darker yellow or a wash and a shade lighter dry brush paint, is this correct? I do not have an airbrush yet so it'll have to be done by brush, iv just never done it and can't find a YouTube video on ss hair repaint, anyone experienced in this? Any advice will be appreciated
