Affinity Photo: Get rid of hue around hair

[Raffiki113]

Hello,
I am trying to get rid of a red hue around hair.
The picture was taken in front of a red background and I was able to get to this point... getting rid of the red hue around the T-Shirt was not too difficult, but the hair is tricky.
I have watched several tutorials but have found nothing that helps to solve this issue adequately.
Thank you for your help.

Hi @Raffiki113,

Welcome to the Affinity Forums

It would be easiest to remove this colour fringe when performing the initial background removal, however using the image you've provided I've been able to achieve the following:

1. Using the Selection Brush Tool, make sure that 'Snap to Edges' on the Context Toolbar is disabled, then create a selection around the red fringing 
2. With this selection active, add a HSL Adjustment
3. Select the red circle in the HSL adjustment, so that we're only changing the red pixels in the image, and reduce the saturation to -90% and close this dialog
4. With the selection still active, add a Selective Colour Adjustment
5. In this dialog, with the Colour dropdown set to Reds, reduce the Magenta slider to -100%
6. Change the Colour dropdown to Magentas and again reduce the Magenta slider to -100% and close this dialog
7. Make sure that the HSL Adjustment is above the Selective Colour Adjustment in the Layers Studio, and deselect your selection (ESC).

I hope this helps!

Wow. I am in awe 🙇‍♂️😀
You have no idea how many different ways I tried to get rid of this.

Thank you so much. I learned a lot.

Would you do it any different with the original picture?

This is how I approach these.

• I use the Selection Tool to create a selection of the person.
• In Refine Selection, I will make any necessary adjustments, like using the Matte and brushing the outline.
• Once I get the desired selection, I will use the option of Output> New Layer or New Layer with Mask. The reason for those, they provide Color Decontamination where the other options do not. It seemed to help in your example.
