This has been sitting on my hard drive for ages, half finished. ~BurnNotice
asked me if I would ever do a hair tutorial, so I finished this old thing up for submission. Not quite a hair drawing tutorial, more like a hair color thing, but hey, close enough right?
Oh, and let's pretend the Salt and Pepper colors are black and grey, not brown and grey. Black didn't look right. Feel free to exchange the brown for any other color in the chart (although, with the lighter blonds, trade the grey for more of the white shades).
These colors are the basic ones. You can go darker, or lighter, or change shades entirely. In fact, I encourage you to. But sometimes, it's really nice to have a little cheat sheet for when you don't feel like having to think deeply about your color choices.
mentioned in the comments, you can also use the Hue/Saturation tool (or whatever equivalent your program has) to adjust any of these colors to the exact shade you want. Just be sure to have your hair on a separate layer.
Oh, and by the way, I do happen to do art too, so why don't you give some of the stuff I spend a lot of my time, effort, and tears on some love, okay?
