The Background Depends on You
Three different answers, by complexion and hair.
Nearly every country names one background colour and leaves it there. Jamaica does something more thoughtful and, as far as this site's research goes, unique: it varies the background so that the person always contrasts with it.
Applicants of light complexion should avoid wearing white clothing and should have the photograph taken against a pastel shaded background. Applicants of dark complexion should wear coloured clothing and be photographed against a white background. Applicants with grey or white hair should use a pale blue or pastel background.
The logic is the same one hiding behind every other country's background rule — a face has to be separable from what is behind it — but Jamaica states it as an outcome rather than a fixed colour. Bright coloured clothing is not recommended in any case.
This is worth knowing before you sit down in a photo booth that only offers white.
