If it's meant to be like natural ginger hair, it needs to be a bit more orange and a bit less saturated, or a bit browner, darker and less saturated (depending on what shade of ginger). Either way it's a bit too fluorescent. If it's meant to be like red as in "dyed bright red" punk hair, then it's probably about right.
[edit, after edit above] I think it looks about right - though can't really tell until someone checks it in game. If it's a bit off, then it's probably only a quick tweak to correct it anyway. Nice one.
