Passports need a white background – Passport Camera -ID Photo Edit Review

They can't be edited for passports either. Your state department website has the guidelines; the US State Department has examples of right and wrong photos. I think there's been an international standard since post World War One. Other options will be fine for "passport style" photos but don't delay your passport application by mistakes in photos.
