/jp/ - Otaku Culture

Hello. I made a little trace based on a friend's character in PSO2. I like to color things but I've never attempted to color hair like artists usually do.

I've looked up some tutorials on SAI but there's so many and every one is always slightly different on regards to layers and selection and clipping layers and brushes used... can /jp/ artists recommend a quick and dirty way or tutorial to color hair that doesn't go too in-depth into the software? I'd rather it be efficient enough that I can get it done in an hour or two and not spend the entire afternoon doing it, because when it gets to that point, I look back at it and realize I'm not satisfied with it at all and get really demotivated to draw.
