Naruto Chapter 498

Red has always been the color associated to the Kyuubi, even its chakra has had a "red feel" to it for who knows how many chapters, so i doubt Kishi had that in mind when he first came up with the orange jumpsuit

Red is the color of and associated with evil, hatred, and anger. The things of which the Kyuubi's energy supposedly consists.

Since Red was invented.

Those are not my own interpretations, those are the characteristics that are attributed to the color red in color psychology. Red is associated with anger, hatred, evil, power, and danger. It can also be associated with passion, courage, lust/sexuality, romance, heat, strength, leadership, and sacrifice.
