How do you say "gray area" in spanish?

Question

The phrase "grey area" could translate to "area gris" but I didn't think that would be right. Does anyone know a spanish phrase that would be equivalent to meaning "grey area" in the context of "Some ethical issues have no clear right or wrong answers because they fall in a gray area".

Thanks

Laguna o terreno desconocido is what I would use.
