To change this lady's hair color... i really expected it to be a whole lot harder but as it turns out it was actually pretty easy. The biggest mistake i made was in the very beginning was supposed to select the brush tool and instead i selected the healing brush so when i switched to quick mask mode the red line would not stay. other than that i fixed it and went to edit>adjustments> hue and saturation then i was finished.
