Orange
From Tardis Wiki, the free Doctor Who reference
Ginger was a dark shade of orange.
The War Doctor wore a double breast waistcoat of ginger moleskin. (COMIC: The Clockwise War) Klineman Halpert of Ood Operations once used the word "ginger" as an insult towards Donna Noble, in reference to the colour of her hair. (TV: Planet of the Ood)
