Hi, if the lighting is just white light, then shades of grey (like this: cdn1.iloveindia.com/lounge/ima… ) . If you have coloured light sources, then obviously more colours are needed. Best probably to do an image search on Google for black hair then you will have a good reference. Here a couple of my portraits with very dark hair:
Awesome! Yeah, it's what I did on my first portrait (Of course the hair looked terrible, but that was from the edgings). Thanks for the help! Now, I'm going to take what I've learned, and do something (hopefully) amazing with it!
You sure have patience... I also don't like drawing hair, at all, especially when we have to draw traditional portraits in school... but I dare to say you paint hair quite well :3 My favourite part is the one with blurry hair over shoulders, it looks like those professional photo portraits, and it really draws attention to face.
