Change the background color

[mkahsan]

I am not an expert, I do basic editing using the Affinity Photo 2 app on my Mac/iPad Pro. Couple of weeks back I took this photo of star trail using an iPhone app (ReeXpose). The iPhone app creates a purple background in the dark which I would prefer to be dark blue. Is it possible to change the color in the Affinity app? Any help will be greatly appreciated.

@mkahsan Welcome to the forums.

You could use a Colour Balance Adjustment, set the Tonal Range to Shadows and reduce the Cyan/Red slider.

Another possible workflow is to use an HSL Adjustment, narrowing the range to purple/dark purple and then adjusting the Hue shift.

Thank you Lee. Color balance adjustment did the trick.
