Can I change the background colour after removing it?
Yes. After removal, the editor lets you keep the background transparent or switch to white, black, blue and other solid colours, gradient and studio backdrops, a blurred version of the original, or your own photo — then add a shadow or outline and download.
Solid white is the one most people need for passport, PAN and marketplace photos; the editor's White preset gives a flat, even white rather than a photographed wall. Gradients and studio backdrops suit thumbnails, profile pictures and product hero shots.
Via the API, pass bg_color=ffffff (any hex) to get the solid colour directly; transparent is the default. The editor guide shows every option.
