Changing the colour of hair in GIMP

First, you need to open your image and then duplicate it in the layers panel by right-clicking and selecting ‘Duplicate Layer’. Once you have your duplicate layer, go over to the ToolBox and select the Zoom Tool. This will let you zoom into the area you’re working on and make it easier for you to apply changes to the image.

Go to the ToolBox and select the Paths Tool and then go around the hair, carefully selecting it all. This is worth spending quite a bit of time over to ensure the hair is selected correctly. Then once you’re ready go to Select>From Path to form a path of ‘running ants’ around the hair.


Next, go to Colour>Colour Balance to open the Colour Balance Window. Here you can pick colour levels and the range you want to adjust. Once you’ve played around with the sliders and are happy with the changes, click ok.

Finally go to Select>None to deselect the image and zoom back out to see the final results.
