What is french for the colour ginger?

There isn't a direct, single-word translation for "ginger" as a color in French. You would typically describe it using a phrase:

* "Couleur gingembre" (ginger color)

* "Rouge orangé" (orange-red)

* "Brun roux" (reddish brown)

The best choice would depend on the specific shade of ginger you are trying to describe.
