As a new XaraX-ite I guess I'm still thinking in terms of paint programs, because I can't figure out what should be a simple procedure.

I have an imported GIF which has a uniform black background.

My goal is to change the color of the background, leaving everything else as-is - or maybe even make the background transparent.

I've tried tracing - looks like crap. Really don't want to do a manual cutout as the image to be kept is quite complex. Any filling I try to do affects the whole GIF.

TIA for any help.
