adhesive polyester films are available from Oracal in silver, chrome, and gold, (oracal 351) and white/screen- or uv- printable (oracal 352).
Avery has a similar selection, and one that I believe is latex-printable as well.
3M has the PVC-Free solvent- and latex-printable Envision materials, but those are pretty expensive.
Most of the printable options would require you to put the graphic on the outside of the door.
Without printing, you will have way more color options with PVC-based products if you have access to a plotter.
