im trying to colourise someone with orange hair to make the hair black, but the only way i know how either does nothing to it, makes it a brighter red, or makes it gray. this is in photoshop. can anyone help?
Hmm. I don't think I often use photoshop "correctly" lol. I don't know all the technical ins and outs, but...you've figured out a way to isolate just the hair? By using the magic wand tool or a clipping path or whatever?
Once the hair is selected, isolated, I'd personally just go to the top menu bar, then go to image, then adjustments, then hue/saturation. I'd bring the saturation way down so it's almost black/gray. And you can adjust the hue as well.
You can also fine tune it, adjust it by going to image/adjustments/variations. You can add more blue, cyan, yellow, make it lighter or darker, etc, etc.
