i can't see any image/link attached.Anyway when the image has no transparency it's gonna be hard to just change the color of specific pixels. Since this involves some image recognition.
When the background is always black you may have a chance to clip away the lack background color using composition.
But it's tricky and i am not experienced with it myself, but i know its possible.

This is the test image.
Its not trivial to remove the background if to look ok after.
Maybe this can give inspiration

so for such "complex" images Qt wont be the right framework to achieve acceptable results
